Suppression of martensitic transformation in Ni-Mn-In metamagnetic shape memory alloy under very strong magnetic field

The magnetic field induced martensitic transformation (MT) and its arrest exhibited by the prototype Ni-Mn-In metamagnetic shape memory alloy have been studied for two distinct states achieved different cooling routes, namely, a zero (ZFC) strong (SFC). For that, magnetization as function of up to 33 T was measured at constant temperatures. As result, phase diagrams “MT versus temperature” were obtained ZFC SFC samples. entropy difference between aforementioned attributed microstructures formed in along each route.
