Research Interests:
Experimental physics in condensed matter physics and materials science – interests extend from rare earth magnetism to nanostructured and spin crossover materials.
Structural and magnetic properties - investigated using a variety of techniques - x-ray and neutron diffraction, Mössbauer effect spectroscopy, MuSR (Muon Spectroscopy); DC and AC magnetic measurements - other techniques used as required.

Biography
• Completed PhD at Monash University in 1974 after BSc (Hons) and MSc degrees at Aberdeen and Salford Universities respectively; cryogenic research and development with Oxford Instruments (1974-1976); returned to Australia for Research Fellowship at UNSW@Duntroon (1976-1979, Faculty of Military Studies of UNSW, Royal Military College, Canberra); Research Fellow at the Australian National University (1979-1983) before return to UNSW@Duntroon as Lecturer in the Department of Physics (1983-1986).
• 1986 - automatic transfer from UNSW@Duntroon to UNSW@ADFA on establishment of the University College of the Australian Defence Force Academy.
• 1986-2007 - based at the School of Physics and now the School of Physical, Environmental and Mathematical Sciences, UNSW@ADFA - successive promotions to Senior Lecturer, Associate Professor and Professor leading to award of Emeritus Professor in 2005.
• Several research or special studies programme (SSP) visits overseas including terms as Alexander von Humboldt Research Fellow - University of Saarlandes (1983; 1989); SSP at University of Reading (1994); SSP at Johannes Gutenberg-Universitaet, Mainz (2000); SSP at FRM-II, Technische Universitaet Muenchen (2003).

Research
Magnetism of Rare-Earth Intermetallic Compounds
Examples:
• Determined the crystal structure of a series of quaternary compounds which we discovered - R3 T29 Si4B10 (R = rare earth; T = Co, Ni) - currently investigating their magnetic structures;
• Mixed magnetic interactions and phase diagram of (La, Y)Mn2Si2and PrMn2-xFexGe2, pressure-induced antiferromagnetism in ferromagnetic LaMn2Si2;
• Magnetic and valence transitions in YbMn2Si2-xGex, EuMn2Si2-xGexsystems
• ErFe12-xNbx; Dy2Fe17-xMnxcompounds ……..
Preparation of New Phases and Materials using Mechanochemical Methods
• Collaborative ball-milling project with colleagues at the Australian National University - formation mechanism of boron nitride nanotubes produced by reactive ball milling; related studies of mechanochemically treated materials based around iron oxides - exhibit novel structural states and physical properties
• Interplay of structural and magnetic properties of nanoscale spinel ferrites e.g. ZnFe2O4 ; MgFe2O4 , NiFe2O4.
Advanced Materials - Mössbauer Spectroscopy at UNSW@ADFA
• Dr Jianli Wang ( University of Wollongong ) will rejoin our group around July/August 2007; this position stems from a joint agreement between the Bragg Institute at ANSTO and UNSW@ADFA - research studies of magnetism materials;
• Strong links with colleagues at UNSW@SYDNEY; ANU; Bragg Institute, ANSTO; Germany (Muenchen; Mainz; Darmstadt; Karlsruhe); Belgium; UK
