The kinetics of development of strain-induced magnetic anisotropy Kus has been studied in a zero-magnetostriction metallic glass Co65.2Fe4.2Ni3Nb1Al2Si9.8B14.8. The variations of Kus with annealing time ta involve the effect of a wide distribution of relaxation times. It was found that △E = 180-290kJ/mol and τ0=10-14-10-22s for 155 MPa isothermal annealing at 280-320℃ after 244MPa annealing at 440℃.
