Science on MARI
17 Oct 2008



The science program run on MARI is dominated by studies of magnetic excitations in powder and polycrystalline materials.


I​nvestigations of magnetic materials account for around two-thirds of the science program.  These studies include:

  • Magnetic excitations in unconventional superconductors
  • Heavy fermion metallic magnets
  • Frustrated and low-dimensional magnetism
  • Transition metal oxides (3d, 4d and 5d, spin-orbit coupling)

Of the remaining one-third of experiments, studies performed include

  • Phonon DOS in crystal systems and comparison with ab initio results
  • Chemical physics; DOS of chemical systems and chemical systems on substrates (i.e. catalysts) Excitations of H. Here MARI has a symbiotic relationship with TOSCA in that MARI offers far better Q resolution, and the ability to look at high energy excitations at relatively low Q.
  • Collective excitations in ionic liquids

The current scientific program on MARI has shifted decisively toward magnetic excitations – this emphasis was not originally the case for MARI for the first 15 years of its operation, when the majority of experiments performed were on liquids and disordered materials.
