The magnetic, transport and thermal properties of single crystal Co2FeGa have been investigated. The small coercivity 20 Oe and saturation field 4000 Oe of Co2FeGa sample at temperature 5 K indicates that the single crystal is magnetically soft. The resistivity (ρ) behaves according to ρ ∼ T1/2 power law below temperature T = 40 K, which is due to electron-electron interaction effects in the presence of disorder. The thermal conductivity of Co2FeGa single exhibits anomalous temperature dependence above 50 K, i.e., the conductivity increases with the temperature, or dκ/dT > 0. We conclude that this anomalous thermal conductivity is due to the strong atomic disorder between the Fe and Co atoms.
