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