“…Unlike the Ga-based alloys, the Ni-Mn-Sn alloy has an irreversible field-induced transformation from martensite to austenite, similar to the case of Ni 50 Mn 37 Sn 13 [19,20]. Along with field-induced transformation, a large negative magnetoresistance around the martensitic (MT) temperature, as well as an inverse magnetocaloric effect, have been observed in these alloys [21,22]. Together, these findings provided the motivation to understand detailed structure-property relationships in the off-stoichiometric Ni-Mn-Sn Heusler alloys.…”

“…The very basic property of electrical resistivity in metals is modified by the presence of disorder in the crystalline system. In the off-stoichiometric Heusler alloys, martensitic transformation and disorder effects (site and magnetic) significantly modify the electrical resistivity 48,49 . The martensitic transition enhances the structural and magnetic disorder in the system.…”

The Heusler alloys that exhibit reversible martensitic transition show multifunctional properties including magnetic shape memory effect. The properties of two kinds of magnetic shape memory alloys are studied, where magnetic field-induced strain is driven by two different mechanisms. The properties differ in martensitic phase with composition and thus they are studied in martensitic phase. The crystal structure (Xray diffraction), magnetic behaviour (SQUID), transport analysis (four-probe method), magneto-transport trend (up to 8 T), magnetocaloric effect (around room-temperature), electronic structure (X-ray photoelectron spectroscopy and ab initio calculation), surface characterization (ultraviolet photoelectron spectroscopy and inverse photoelectron spectroscopy) are discussed for the matensitic phase. Analysis of the properties reveals alloys with possible applicability at room temperature with low magnetic field.

“…In the present case, the increase in resistivity for the 50 kOe curve is believed to be not due to the effect of field. This is because, in some similar Heusler alloy systems, it is observed that the thermo-resistivity curve taken in a higher field follows a lower resistivity path [16,30]. The lower resistivity in these cases was attributed to the supercooling of the high temperature and low resistive austenite phase to low temperatures.…”
