Nature of Exchange Interaction in Amorphous Alloys Based on Metals of Iron Group with Metalloids

The temperature dependence of magnetization is studied to obtain information about the nature of structural and magnetic transformations in amorphous alloys. Low-temperature magnetization provides information on spin waves, i.e., the law of 'three second' T 3/2 is fulfilled. The spin-wave rigidity constant D, a characteristic property of an amorphous ferromagnetic, is determined from these dependencies.
