Abstract
- The single crystal Ni54Fe19Ga27 shows a martensitic transformation at 281 K on cooling and 283 K on warming. Large jumps in the temperature-dependent resistance curve, temperature-dependent magnetization curve and temperature-dependent thermal conductivity curve are observed at the martensitic transition temperature (TM). Negative magnetoresistance due to spin disorder scattering was observed in Ni54Fe19Ga27 single crystal in all temperature ranges. The Ni54Fe19Ga27 sample exhibited a temperature dependence of thermal conductivity κ(T)(dκ/dT>0) due to atomic disorder above a temperature of 50 K.
