Abstract
The evolution of magnetic parameters obtained from hysteresis loop (coercive field H c and reduced remanence m r) with current annealing in the amorphous wires Fe 77.5Si 15B 7.5 has been determined. Kinetics of the results are interpreted in terms of an activation energy spectrum model. Two different processes seem to be present during the treatment, which can be connected with the two magnetic regions assumed for this amorphous wire.
