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.

Key words: amorphous alloys, spin waves, magnetization, magnetic moment, Curie temperature, exchange interaction parameter.
