Abstract

The field dependence of the magnetization of a ferromagnetic Heusler alloy Co2CrGa has been measured close to the Curie temperature of 488.0 (0.3) K up to an applied field of 50 kOe. The critical exponent δ has been determined to be 4.93 (0.30). The result is described by the theory by Takahashi for a weakly ferromagnetic itinerant electron system rather than by a conventional molecular field theory.
