E. Lopez et al., INFLUENCE OF DOMAIN-WALL STABILIZATION ON DYNAMIC LOSSES IN AMORPHOUSRIBBONS, Journal of magnetism and magnetic materials, 133(1-3), 1994, pp. 74-76
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.
