摘要：

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 (T-C) of the sample is found to be 333 K. The magnetization versus field (M-H) curve at 5 K and 300 K shows existence of ferromagnetic order in the alloy. The resistivity of the alloy varies as T-2 at low temperature and as T at high temperature. Above T-C, sharp flattening in resistivity is observed. The negative MR of -1.7% is observed at 300 K and is found to increase linearly with the magnetic field. (c) 2013 Elsevier B.V. All rights reserved.
