Sažetak
The measurements on amorphous ferromagnetic ribbons have shown that direct (JD) and alternating (JA) core-current can affect the M-H loop and cause effects like decrease the coercive field Hc (hence decrease hysteresis loss E), shift the center of the M-H loop (C) along the H-axis, and change the permeability, maximum (Mm) and remanent (Mr) magnetization of the sample. These effects are associated with transverse field Hp generated by JD (static Hp). The magnitude of Hp increases linearly with the distance from the center of the ribbon and reaches the maximum at its surface, hence the term “surface field”. The influence of surface fields Hp on the parameters of M-H loops of amorphous and nanocrystalline Fe73.5Cu1Nb3Si15.5B7 ribbon and amorphous VITROVAC 6025Z ribbon has been investigated [1, 2]. In amorphous Fe73.5Cu1Nb3Si15.5B7 ribbon Hc decreases with Hp with unchanged Mm, whereas in nanocrystalline Fe73.5Cu1Nb3Si15.5B7 and VITROVAC 6025Z ribbons Hc increases with Hp and Mm decreases with Hp. This unusual increase of Hc with Hp is ascribed to the influence of Hp on the surface domain structure (SDS) and strong interaction between SDS and inner (main) domain structure (MDS) in these materials. A model is developed which takes into account this influence and explains the experimental results [3].
