Abstract

We report a magnetocaloric effect with nearly zero thermal hysteresis in Heusler alloy of Ni₅₀Mn₃₆Sb₈Ga₆ around room temperature due to a ferromagnetic transition in martensitic state (FTMS). The refrigerant capacity value of this ferromagnetic transition in the vicinity of onset temperature T C M can arrive at 163.8J/kg, much higher than that of first-order magnetically martensitic transition in the same alloy. Such a magnetocaloric effect in FTMS is attributed to a second-order (or a weak first-order) transition from an antiferromagnetic phase with modulated 7M orthorhombic structure to a ferromagnetic phase with modulated 4O orthorhombic structure.
