Description

The magnetoresistance (MR) behaviour and the magnetocaloric effect (MCE) of the ferromagnetic shape memory alloy of nominal composition Ni2Mn1.36Sn0.64 have been investigated. We observe giant negative MR (∼ - 48% at 90 kOe) around the martensitic transition (MT) temperature. The observed MR was found to be irreversible with respect to the applied magnetic field, particularly in the vicinity of MT. The sample exhibits a large but positive magnetocaloric effect (a peak value of 5.1 J kg-1 K-1 for the magnetic field changing from 0 to 20 kOe) around MT. A comparison with the other Ni-Mn-based shape memory alloys indicates that the observed MR scales with the magnitude of the MCE.
