Dr Hicks' research interests are in the area of magnetism primarily using the neutron probe. However extensive use is also made of bulk magnetic measurements and the Mössbauer effect as well as other techniques for specimen characterisation.
Disordered magnetic materials are of most interest, particularly spin glasses, antiferromagnetic mixed compounds and alloys. The limits to stability of these phases is investigated in quasi-two and three-dimensional structures.
Much of the work involves the use of neutron polarisation analysis to individually characterise the magnetic and nuclear contributions to the neutron scattering. Neutron polarisation analysis, combined with fast pulsing of the neutron spin flipper is also used for neutron spectroscopy on both magnetic and non-magnetic materials.
Dr Hicks currently holds two ARC large grants, one of which is for the investigation of disordered and low dimensional magnetic systems and the other is for neutron crystal field spectroscopy of quantum critical rare-earth intermetallic compounds and alloys. In addition, work on a third ARC large grant is now concluding. The purpose of this grant was to experimentally confirm results predicted by an ab-initio theory of magnetic alloys.
