On average between 2011 and 2014, investigations 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.
