  • ABOUT
  • PUBLICATIONS

Glen has a BSc (Honours), PhD in Physics and a Dip. Ed. from Monash University. His research involves the application of hyperfine interaction techniques (in particular 57Fe-, 169Tm- and  161Dy-Mössbauer spectroscopies) to probe electronic and magnetic interactions at the atomic level.

Recent research interests include:-

  • The nature of crystal field and magnetic interactions in rare earth compounds and intermetallics that exhibit interesting bulk behaviour
  • Magnetic properties of rare earth perovskite-related materials
  • Minerals and mineral refining processes
  • Radar absorbing materials and biomagnetic materials
