Abstract

Precise magnetization measurements have been made on the weak itinerant electron ferromagnet CoVSb. The magnetic moment at 4.2 K and the Curie temperature T _C are 0.16 μ _B/f.u. and 45 K, respectively. Below 10 K, the decrease in the square of the spontaneous magnetization M _s(T) ² is proportional to T ². However, over a wide temperature range from 24 K to the Curie temperature, the decrease in M _s(T) ² is proportional to T ^4/3. The results obtained are analyzed using spin fluctuation theory.
