Abstract

The structural, magnetic and transport properties of the newly synthesized Ni35Mn50In15 alloy have been presented. It was observed to form in single phase Hg2CuTi-type structure. The Curie temperature (TC) of the sample is found to be 333K. The magnetization versus field (M–H) curve at 5K and 300K shows existence of ferromagnetic order in the alloy. The resistivity of the alloy varies as T2 at low temperature and as T at high temperature. Above TC, sharp flattening in resistivity is observed. The negative MR of −1.7% is observed at 300K and is found to increase linearly with the magnetic field.
