Description

The field dependence of the magnetization of a typical itinerant ferromagnet CoS2 has been reinvestigated close to the Curie temperature of 119.5 (0.5) K up to an applied field of 50 kOe. The critical index δ has been determined to be 5.2 (0.20). The result is in agreement with the theory by Takahashi for weak itinerant electron ferromagnets rather than the conventional molecular field theory. Reliable method for determining critical indices is also discussed.
