Nishihara, Y. Furutani, T. Wada, T. Kanomata, K. Kobayashi, R. Kainuma, K. Ishida, T. Yamauchi] The field dependence of the magnetization of a ferromagnetic Heusler alloy Co2VGa has been measured close to the Curie temperature of 358K up to an applied field of 50kOe. Results for samples with different Curie temperatures of 351K are also reported. The critical exponent δ has been determined to be 4.15 (0.05) for both samples. The value is different from either 5 predicted by the spin fluctuation theory by Takahashi or 3 derived by a conventional molecular field theory. Possible origins for the discrepancy from the theories are discussed.
