Abstract

We report the magnetism and magnetic entropy change in the Mn-rich Ni48Mn39Sn13 Heusler alloy system. The excess Mn content stabilizes the cubic austenite phase at room temperature. The shift of Martensitic transition temperature to low temperature with the application of higher magnetic field. A magnetic entropy change (“SM) of 12.12 Jkg−1K−1 has been achieved for a field change of 5 T for this alloy
