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.
