The Influence of Domain Structure on the Variation of Coercive Field and Maximum Magnetization of Fe_77.5B_22.5 Amorphous Alloy
The magnetic hysteresis of Fe_77.5B_22.5 amorphous ribbon has been studied by the induction method. The results for coercive field (H_c), maximum magnetization (M_m) and remanent magnetization (M_r) are explained by the twofold domain structure of amorphous alloys in form of ribbons. The analysis of the measurements shows that the inner domains are responsible for the magnetization up to about 65% saturation magnetization (M_s) and that the interaction between two domain structures plays an important role in enhanced increase of H_c on M_m>0.5M_s. The frequency dependence of parameters of the hysteresis curve is briefly discussed.
