Abstract
Abstract The fundamental magnetic properties of transition metal-metalloid amorphous alloys are summarized. Particular emphasis is placed on comparing the effect on the properties of long range structure disorder versus the effect of the change in the electronic environment due to the metalloid. The induced anisotropy due to magnetic and stress annealing is also reviewed. Low coercivities and losses and high permeabilities are achieved in a number of alloys after a stress-relief anneal as a result of the averaging of the local crystal anisotropy. It is concluded that the amorphous alloys are a promising new class of soft magnetic materials for applications in competition with conventional NiFe, FeCo and FeSi alloys.
