中文摘要	The magnetic, thermal, and transport properties of martensitic phase transformation in single crystal Co(5)Ni(2)Ga(3) have been investigated. The single crystal Co(5)Ni(2)Ga(3) shows martensitic transformation at 251 K on cooling and 254 K on warming. Large jumps in the temperature-dependent resistance curve, temperature-dependent magnetization curve, and temperature-dependent thermal conductivity curve are observed at martensitic transformation temperature (T (M)). Negative magnetoresistance due to spin disorder scattering was observed in Co(5)Ni(2)Ga(3) single crystal at all temperature range. The temperature-dependent negative magnetoresistance shows a peak at T (M), which indicates that the spin disorder increases in the process of phase transition. Co(5)Ni(2)Ga(3) sample exhibits a temperature dependence of thermal conductivity kappa(T) (d kappa/dT > 0) due to electrons being above temperature 100 K.
