Metallic glasses as nonsaturated ferromagnets

The decrease in spontaneous magnetization per atom during the amorphization of 3d-ferromagnets is explained by proceeding from the concept of ferromagnetic metallic glasses as nonsaturated ferromagnets. The spontaneous magnetization and longitudinal magnetic susceptibility are determined at T = 0, and the temperature dependence of spontaneous magnetization at low temperatures is analyzed. The experimentally observed discrepancy between the spin wave rigidity and the coefficient in Bloch’s 3/2-law is explained.
