Abstract

The single crystal Ni 54 Fe 19 Ga 27 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 (T M ). Negative magnetoresistance due to spin disorder scattering was observed in Ni 54 Fe 19 Ga 27 single crystal in all temperature ranges. The Ni 54 Fe 19 Ga 27 sample exhibited a temperature dependence of thermal conductivity κ (T) (d κ / d T > 0) due to atomic disorder above a temperature of 50 K.
