Sažetak
The effects of abrading with sandpaper the surface of VITROVAC 6025Z ribbons on the parameters of their M-H loops (the coercive field Hc, the position of the centre C, the maximum magnetization Mm, etc.) has been investigated. The application of surface fields HP (generated by core currents) enabled us to single out the effects of surface domains (SDS pinning) and surface irregularities (intrinsic pinning) on domain wall (DW) pinning in abraded and unabraded ribbons. The abrasion enhances the intrinsic DW pinning (increases Hc) and strongly modifies the SDS pinning which shows up in specific variations of Hc and C with HP. In particular, the effect of HP on SDS pinning which was symmetrical in unabraded ribbon becomes asymmetrical upon abrasion (i.e. different on opposite surfaces). Simple model for the influence of HP on magnetisation processes in very soft magnetic ribbons describes well the observed variations of Hc and C with HP in both abraded and unabraded ribbons. The use of abrasion in order to tune the effects of oblique fields on M-H loops of very soft magnetic ribbons is briefly discussed.
