  Advanced Materials

The School of PEMS hosts the web site of the Condensed Matter and Materials topical group of the Australian Institute of Physics.

Scholarship available - from 1 January 2011 - explore the structural and magnetic properties of novel magnetocaloric materials and related aspects in magnetic cooling .

The Advanced Materials group is actively engaged in the investigation of the properties and behaviour of materials with topics as diverse as:

In most instances, atomic or nuclear probes are used to study the microscopic properties of the materials involved or their spectroscopic ?fingerprints? are used to identify and quantify the amounts of materials and phases present.

The key nuclear probe techniques employed include M?ssbauer spectroscopy (57Fe as well as rare earth resonances such as 169Tm, 161Dy) and the very low temperature techniques of Nuclear Orientation (NO) and Nuclear magnetic Resonance on Oriented Nuclei (NMRON). Perturbed angular correlation (PAC) measurements are conducted in collaboration with Prof. Aidan Byrne of the ANU, who was closely associated with the development of the joint radioisotope implanter that is sited here at ADFA. Where radioactive nuclei are employed, they are either diffused into the specimens or implanted using the radioisotope implanter. Sometimes they are activated in situ via neutron irradiation at the Lucas Heights reactor facility. The process of ion implantation is of interest in its own right and is investigated using our School's radioisotope implanter as well as in collaboration with researchers at other facilities.

The in-house atomic probe technique is that of pulsed and swept-field electron spin resonance (ESR). Although this facility was designed specifically for the quantum computing project, it opens up exciting new possibilities for the study of other dilute magnetic systems.

These microscopic techniques are used in combination with x-ray and neutron powder diffraction, specific heat, and bulk DC magnetisation and AC susceptibility measurements. In addition we perform experiments at national and international large facilities, to perform neutron scattering and advanced x-ray scattering.

Neutrons are very valuable for determining, among others, solid state properties. Due to their neutral charge, they penetrate deeply into materials, allowing for the determination of bulk properties. In addition, due to their spin magnetic moment, they interact with the electronic magnetic moments, allowing the study of magnetic properties such as magnetic structure determination or magnetic excitations. Crystallographic and dynamic properties of the solid are obtained via the energy and momentum transfer of the scattered neutrons.

Synchrotrons produce high intensity x-ray beams that are suited for characterization of, among various others, the solid state. Due to the high x-ray intensity, small changes in structure, charge density as well as magnetic properties are readily observed. A large advantage is that the energy of the incoming x-ray beam can be tuned to certain absorption edges (resonances) of the material. This way, element specific properties can be determined independent of the bulk properties of the material.

One of the two new Perturbed Angular Correlation Spectrometers at UNSW@ADFA produces first results.

Research Agreements

Academic exchange between UNSW@ADFA, School of PEMS and the University of Toyama, Graduate School of Science and Engineering

Prof. Katsuhiko Nishimura from the University of Toyama is a regular visitor to UNSW@ADFA. His long standing collaborative research work with Dr Wayne Hutchison and the Advanced Materials Group was the basis of an agreement for academic exchange between UNSW@ADFA, School of PEMS and the University of Toyama, Graduate School of Science and Engineering. The agreement was instigated some 5 years ago and was recently renewed.

Joint agreement between UNSW and ANSTO

We investigate? multiferroic materials using Raman and Neutron scattering (ARC discovery project 2011-2013) between Clemens Ulrich (UNSW, Kensington), Annemieke Mulders and Garry McIntyre (ANSTO).

Current Research

Magnetic resonance
Dr Wayne Hutchison with Prof. Martin Brandt, Dr Jeff McCallum, Dr Paul Spizzirri, Dr Matt Sellars, Dr Stephen Harker

The broad aim of this program is the use of magnetic resonance, directly, for measurements on spin systems which have application as spin based quantum computers (QC). The technique is also applied to investigations of the principal materials and fabrication processes. The emphasis is on electron spin resonance (ESR) studies of the phosphorus-in-silicon (Si:P) system:

Pulsed ESR for coherence time measurements

One of the attractions of a spin based quantum computer is the prospect of long coherence times. In this project, pulsed ESR is applied to ensembles of phosphorus spins in silicon to explore this experimentally. The spin coherence time is expected to increase with reduction in temperature and of the concentration of both the phosphorus donors and host 29Si isotope (non-zero nuclear spin). A pulsed ESR system has been developed that can operate in conjunction with an electro-magnet down to 4 K, or with a dilution refrigerator and superconducting solenoid magnet down to millikelvin (mK) temperatures.

Swept field ESR measurements

Conventional (swept field) ESR is also used to investigate large area Si:P implants (ensembles) produced via implantation of P+ and molecular P2+ at the University of Melbourne . Focus continues on examination of various preparation methods with a view to maximise donor activation, as viewed by ESR, and to minimise unwanted charge traps.Electrically detected magnetic resonance (EDMR) is also used as a much higher sensitivity and surface senstive alternative. ESR is also applied to systems of interest for optical NMR based quantum computing such as EuCl3.6H2O.

Novel multiferroic materials for the next generation of microelectronics
Annemieke Mulders, Clemens Ulrich, Garry McIntyre (ANSTO)

Multiferroics are advanced materials which exhibit strong electric and magnetic polarizations simultaneously. They are promising candidates for novel applications with the potential to dramatically increase data storage capacity and processing speeds. However, the underlying physics is not yet understood. Competing theories of inherent electronic structure and ionic displacement have attempted to explain the coupling of the polarizations, but no experimental evidence currently exists to distinguish between the models. This project focuses on the electronic and magnetic properties, to clarify the nature of multiferroic coupling and to help develop new materials for future industrial applications.

Investigation of multiferroic materials using neutron and resonant x-ray diffraction
Annemieke Mulders, Wayne Hutchison, Maciej Bartkowiak, Andrew Princep, James Hester (ANSTO), Chris Ling (USyd), Urs Staub, Katja Pomjakushina et al? (PSI, Zwitserland).

Resonant X-ray diffraction (RXD) is a powerful technique to study charge, orbital, and magnetic arrangements. Tuning the energy of the incoming x-rays to an absorption edge permits recording Bragg reflections with enhanced sensitivity to the specific ion and its electronic configuration. Neutron diffraction is particularly suited to investigate magnetic order. The combination of both techniques is used to investigate the multiferoic properties.
We investigate LuFe2O4, a compound that is multiferroic due to charge frustration [PRL 103, 077602 (2009)] and the multiferroic spiral magnet hexaferrite, using x-rays tuned to the Fe L-edge, which probes directly the properties of the 3d electrons. [PRB 81, 092405 (2010)]

Characterization of III-V semiconductors with ion beam analysis and radioisotope probes
Assoc. Prof. Heiko Timmers, with Dr S. Shrestha, Dr S. Butcher, Dr M. Wintrebert- Fouquet, Prof. A. Byrne,
Prof. R. Vianden & Dr W. Zeitz

The increasing demand for wireless communications systems requires faster transistor operating speeds. For many applications, high power, high temperature operation is also needed. The fundamental physical properties of the group III-nitrides GaN and InN suggest that they should outperform Si, and also GaAs, in high-frequency applications. InN is expected to provide the highest operating frequencies while still at high power. In collaboration with Macquarie University in Sydney and others the growth of GaN and InN films is developed to achieve quality material for commercial applications. High precision analysis of the film composition is achieved using Elastic Recoil Detection (ERD) analysis. In addition, in order to study the role of defects and to test important processing steps, radioisotopes are implanted into GaN and InN. The subsequent decay of these probes is then observed with Perturbed Angular Correlation (PAC) spectroscopy.

Elastic recoil detection analysis of materials
Assoc. Prof. Heiko Timmers with Prof. R. Elliman

Elastic Recoil Detection (ERD) analysis is an ion beam analysis technique which enables the quantitative compositional depth profiling of materials and thin films. In contrast to Rutherford backscattering (RBS) spectrometry, with ERD analysis an individual depth-profile can be resolved for each chemical element. With very heavy ion projectile beams the sensitivity can be extended to span the periodic table. In order to improve the efficacy of ERD analysis, new design concepts for gas-ionisation detectors have been built and tested.

Fusion dynamics and scattering
Assoc. Prof. Heiko Timmers with Dr M. Dasgupta & Prof. D. Hinde

The relative motion of two nuclei colliding at energies spanning the Coulomb barrier is coupled to other degrees of freedom of this binary system with the consequence that the binary system encounters a distribution of potential barriers rather than a single barrier. While barrier distributions can be probed in fusion experiments, it has been shown in this work that some information about the barrier distribution may also be obtained with measurements of quasi-elastic and elastic scattering. Experiments on the system 40Ca+96Zr suggest that multi-neutron transfer may play an important role in the fusion of heavy systems, as has long been postulated. Quasi-elastic scattering measurements are performed to test this postulate. The results are relevant to the laboratory synthesis of super heavy elements.

Radioisotope tracing of sediment transport
Assoc. Prof. Heiko Timmers & Dr Wayne Hutchison with Assoc. Prof. Jacky Croke, Dr Chris Thompson & Dr J. Fernandez-Niello

Sediment transport along rivers and creeks is an important environmental issue. In this work we have established measurement facilities in the School to quantify sediment transport using the radioisotopes Cs-137, Pb-210 and Be-7. Experiments in progress are relevant to the Fitzroy river basin and local ACT forest management.

Rare isotopes as tracers of prosthesis debris
Assoc. Prof. Heiko Timmers & Dr Laura Gladkis with Assoc. Prof. P. Smith, Dr J. Scarvell & Dr J. Fernandez-Niello

The incidence of knee replacement surgery in Australia (~ 30,000 per year) is rising annually by about 10%. The established bearing material for knee prostheses is ultrahigh molecular weight polyethylene (UHMWPE) which is superior to any other. However, particulate wear debris delaminating from the UHMWPE component causes an inflammatory reaction that breaks down the bone, unfastens the prosthesis and can result in severe pain. Due to increasing life expectancy, many patients need several surgical interventions over their lifetime. Knee replacement surgery costs typically $15,000, imposing a high annual burden of half a billion dollars on the Australian health budget. In this project, we measure the dynamics of wear debris shedding from UHMWPE in knee prostheses with the unprecedented accuracy of rare isotope tracing and accelerator mass spectrometry.

 

Magnetic properties and magnetocaloric effects
Emeritus Professor Stewart J. Campbell and Dr Jianli Wang

The overall aim of this project is to investigate the magnetic and structural properties of a wide range of materials using techniques such as magnetization, M?ssbauer spectroscopy and neutron diffraction. These projects are undertaken in collaboration with colleagues from Australia, Germany, Belgium and China. A particular emphasis is the search for suitable materials that exhibit giant magnetocaloric effects associated with field-induced and temperature-induced first order magnetic phase transitions. Current materials under investigation include:

 
Mechanochemical methods and nanostructured materials
Emeritus Professor Stewart J. Campbell and Dr Jianli Wang

Stewart Campbell has had a long involvement with projects that investigate the phases and reaction processes of mechanochemically treated materials that exhibit novel physical properties. Most recently, this work has addressed iron oxides in collaboration with researchers at the Australian National University and, in particular, the structural and magnetic properties of nanoscale spinel ferrites (e.g. ZnFe2O4 ; MgFe2O4 ; NiFe2O4 ) in collaboration with the University of Braunschweig, Germany.

M?ssbauer spectroscopy as a tool for monitoring ore refining processes
Assoc. Prof. Glen Stewart with Dr Randolph Pax

Work in collaboration with Dr Randolph Pax of RAP Innovation and Development, exploits the phase analysis capability of 57 Fe-M?ssbauer spectroscopy, in combination with x-ray powder diffraction, for investigating minerals and mineral refining processes. Recent investigations included the reduction stage in the production of synthetic rutile from mineral sands and the processing of local porphyry Cu/Au deposits.

 

Nature and influence of the crystal field interaction at the rare earth site in intermetallic compounds
Assoc. Prof. Glen Stewart, & Dr Wayne Hutchison with Dr Paul Gubbens, Assoc. Prof. Hiko Nishimura & Prof. Dominic Ryan

The crystal field interaction acting at rare earth sites plays an important role in determining the alignment of the magnetic moments, both in potential permanent magnet materials and in weaker magnetic systems exhibiting more subtle behaviour. In intermetallics, the interaction is complicated by the presence of itinerant electrons and experience tells us that the most reliable crystal field characterisations employ a combination of experimental techniques.? On-going investigations include (i) an on-going systematic investigation of the crystal field interaction for the isostructural series RT2Si2 (R = rare earth, T = Cu, Ni, Co, Fe, Mn, Cr) and (ii) the crystal field origins of intriguing magnetic behaviour exhibited by the intermetallic series RNiAl4.

 
Structural and magnetic properties of rare earth multiferroic manganites
Assoc. Prof. Glen Stewart & Hazar Salama with Prof. Hugh O'Neill, Assoc. Prof. Hiko Nishimura & Prof. Dominic Ryan

M?ssbauer spectroscopy is a powerful tool for probing the local magnetic moments and crystal field interactions at rare earth and transition metal sites in a wide range of ceramic materials.? Most recently, the 169Tm-, 170Yb- and ?57 Fe- resonances have been employed to investigate both the hexagonal and orthorhombic phases of ytterbium manganite (YbMnO3) and thulium manganite (TmMnO3). In particular, the orthorhombic phases were observed to exhibit intriguing thermal hysteresis effects below their antiferromagnetic transitions.


Student Research

Study of Multiferroic Coupling by Neutron Scattering
Marciej Bartkowiak (maciej.bartkowiak@student.adfa.edu.au) PhD
Field of Study - Physics

The project studies ferroelectric and multiferroic properties of mixed oxides, focusing on the isotope-induced ferroelectric phase transition in strontium titanate. The techniqes employed include both neutron and x-ray scattering, and the samples are characterised by applying Raman spectroscopy, specific heat measurements and thermal gravimetry. At the same time predictions of sample properties are derived from first-principle calculations, and especially density functional theory combined with lattice vibration analysis.

Study of the Production Techniques and Magnetism of Transition Metal Nanoparticles
Anwaar Malik (a.malik@student.adfa.edu.au) PhD
Field of Study: Physics

Magnetic nanoparticles are of interest for a range of applications. Such particles embedded in a protective matrix with precision positioning may find application in data storage. In this project nanoparticles of elemental 3d magnetic elements Fe, Co, Ni plus Pt and alloys have been synthesised, via ion implantation and a range of thermal annealing conditions, within 100 nm silica thin films thermally grown on silicon substrates.? The size and spatial distributions of the nanoparticles are determined from transmission electron microscopy of sample cross-sections and the crystal structure from glancing angle X-ray diffraction analysis.? These results are correlated with SQUID magnetisation measurements on the same range of samples.

Characterization of Electronic Multipole Moments in Rare Earth Intermetallic Compounds
Andrew Princep (andrew.princep@student.adfa.edu.au) PhD
Field of Study - Physics

The competition between some combination of Spin, Charge, Lattice, and Orbital degrees of freedom is at the heart of the functionality in many materials that are a current research focus, such as the superconducting Cuprates, Iron Pnictides, Colossal Magnetoresistive Manganites, and Multiferroic materials. Orbital order is specifically important to the properties of Colossal Magnetiresistive Manganites, Heavy Fermion compounds, and some exotic superconductors (such as the hidden-order compound URu2Si2). The family of compounds RB2C2 (R includes Y, Lu, Dy, Tb, Ho, Er) exhibit an array of ordering that includes superconductivity, magnetism, pure orbital order, and combinations of the above. The interplay between these order parameters is especially important because DyB2C2 exhibits the highest known pure orbital ordering temperature, and the magnetic members of this family all have closely related magnetic phases despite the presence or absence of an orbitally ordered phase. My present research focus is the characterization of orbital ordering in the Dy, Tb and Ho Borocarbides with both neutron and synchrotron techniques and the application of tensorial analysis, and the modelling of their ground states through mean field methods.
