Low energy inelastic neutron studies in Ni-Mn-Sn based shape memory alloy

Abstract: The composition Ni2.04Mn1.4Sn0.56 belongs to the group of metamagnetic shape memory alloys and it shows multiple magnetic phases as a function of temperature. In a recent muon spin rotation experiment on EMU at ISIS, these multiple magnetic transitions are beautifully depicted and it clears out some of the doubts regarding the nature of different magnetic phases. The sample shows paramagnetic behavior between two ferromagnetic phases and has a spin glass like ground state. Our main aim is to study the magenteic excitations by inelastic neutron scattering experiment in two different ferromagnetic phases as well as in the intermediate paramagnetic phase and in the glassy ground state. The possible spin excitations in this system is likely to be in the low energy region and for that we would like to propose a low energy (below 3 meV) inelastic neutron scattering experiment on OSIRIS.
