Abstract:
The temperature dependences of the magnetization of ferromagnetic Heusler alloys Co$_{2}Y$Al, where $Y$ = Ti, V, Cr, Mn, Fe, and Ni have been studied at $H$ = 50 kOe in the range 2 K $<T<$ 1100 K. It is shown that the high-field ($H\ge$ 20 kOe) magnetization is described within the Stoner model.
