We report magnetization, magnetoresistance (MR) and magnetothermopower (MTEP) of melt spun Ni 50Mn37Sn13 ribbons which exhibit an austentite to martensite phase transition at a temperature (TM ) ≈ 294 K. Upon cooling from 400 K, dc-resistivity and thermopower show abrupt changes at TM , indicating a...
