Abstract
The M-H loops obtained under different magnetization conditions have been used in order to analyze the coercive field Hc and the energy loss per cycle E for the amorphous Co70.3Fe4.7Si15B10 ribbon. Applying the model for the influence of the surface fields Hp on the magnetization processes in amorphous ferromagnetic ribbons, we investigated the effects of the dynamic field Hp on Hc and E. It is shown that the influence of dynamic Hp on the M-H loop does not depend on the origin of Hc and E (static or dynamic). This result is important both for the future investigations of the magnetization processes in these materials and for the potential applications.
