Abstract The 350℃ isothermal annealing kinetic behaviour and the temperature dependence of the magnetization-and strain-induced magnetic anisotropy constants, K_(um) and K_(us), of the metallic glass Fe_(78)Si_(10)B_(12) have been studied. The K_(um) of positive value varies with annealing time t_a as a linear function of lg t_a and with temperature T in proportion to M_s~(4.6)(T). However, the K_(us) of negative value varies reversibly in a relaxation manner when tension is applied to or removed from the annealed samples and with temperature T in proportion to M_s~(7.5)(T). The behaviour has been qualitatively interpreted using a distortion-directional ordering model.
