Research Profile

Professor Murray’s magnetochemical laboratory has, for many years, been an unofficial centre of excellence for his own work and that of many groups in Australasia and overseas. Facilities include a Squid magnetometer (2-400K, 0-5.5T), AC susceptibility (2-400K, 0-7T), Heat capacity attachment. In the nearby Physics Dept he has strong collaborations in EPR and Mössbauer spectroscopies. Collaborations with AG Wedd and GR Hanson on metal protein and enzyme solutions have led to high impact publications in JACS and J Biol Chem. Some significant achievements in recent years include the first nanoporous spin-crossover material, published in Science (paper 271), a new series of metal dicyanamide molecular magnets (paper 288), magnetic coupling in a new FeMn purple acid phosphatase (with Hanson and Schenk, paper 250). Murray’s research work was recognized in 2003 by the award of the Royal Australian Chemical Institute’s Burrows Medal for inorganic chemstry.

Professor Murray’s research interests are in the areas of molecular magnetic materials and paramagnetic metal proteins and model compounds.

  • Synthesis and magnetic properties of molecular magnetic materials of the coordination polymer type and the large cluster type.
  • Synthesis and magnetic properties of spin-crossover molecular switch materials of the small cluster and extended network/nanoporous types (with CJ Kepert, University of Sydney)
  • Magnetic studies of metalloproteins and model compounds
