High resolution neutron powder diffraction on Ni-Mn-Sn based shape memory alloy showing multiple phase transitions

DOI

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. It is quite essential that one should corroborate the nature of these multiple magnetic phases using complementary technique of powder neutron diffraction. Our main aim is to study the magnetic structure of the alloy at different temperatures (between 10 and 350 K) on WISH time of flight diffractometer.
