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 ( T M ) . 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 ) ( d κ / d T > 0 ) due to atomic disorder above a temperature of 50 K.
