Abstract The magnetoelastic anisotropy of Fe77.5Si7.5B15 glass-coated amorphous microwires is investigated by the law of approach to saturation magnetization in comparison with the ferromagnetic resonance technique. The anisotropy field of the inner core determined by the former method is 7.6×104 A/m, which is larger than the value 2.5×104 A/m measured by the ferromagnetic resonance method. This difference is ascribed to the skin effect and the uneven distribution of the internal stresses. However, the anisotropy field of the outer shell has a negative value indicating that it has an easy basal plane.
