The response of a series of iron and cobalt-based metallic glasses to heat treatment has been examined in terms of the subsequent changes in magnetic properties. Annealing at temperatures below the crystallisation temperature improves the soft magnetic properties for low frequency applications by relief of stresses generated during rapid solidification. Annealing at higher temperatures improves the magnetic properties for higher frequency applications by introducing a small amount of crystals into the structure which refine the domain size and pin the domain walls, reducing excess eddy current loss.
