High-field magnetization of heusler alloys Fe2 XY (X = Ti, V, Cr, Mn, Fe, Co, Ni; Y = Al, Si)

The magnetization curves of ferromagnetic Heusler alloys Fe2 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 ≤ 70 kOe. It has been shown that the high-field (H ≥ 20 kOe) magnetization is described within the Stoner model.
