Abstract:
The magnetization curves of ferromagnetic Heusler alloys Fe$_2$XY (where X = Ti, V, Cr, Mn, Fe, Co, Ni are transition 3d elements and Y = Al, Si are the $s$ and $p$ elements of the third period of the Periodic Table) have been measured at $T$ = 4.2 K in the field range $H\le$ 70 kOe. It has been shown that the high-field ($H\ge$ 20 kOe) magnetization is described within the Stoner model.
