Abstract
The magnetic hysteresis of Fe77.5B22.5 amorphous ribbon has been studied by the induction method. The results for coercive field (Hc), maximum magnetization (Mm) and remanent magnetization (Mr) 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 (Ms) and that the interaction between two domain structures plays an important role in enhanced increase of Hc on Mm > 0.5 Ms. The frequency dependence of parameters of the hysteresis curve is briefly discussed.
