Abstract
Dynamical hysteresis losses in amorphous magnetic materials depend mai nly on the micro eddy currents. This effect can be enhanced by domain wall (DW) stabilization phenomena, since the anisotropy modulation ind uced by a stabilized DW behaves like a pinning plane. The irreversible displacement of a DW that overcomes this kind of defect produces an i ncrease of micro-eddy currents that can be an important part of the to tal hysteresis losses.
