Mechanisms of the influence of electroinsulation coatings on the magnetic properties of amorphous soft magnetic alloys

Abstract
The influence of organic and inorganic coatings on the magnetic properties of amorphous Fe-B-Si-C and Fe-Co-Si-B alloys were investigated. The samples of these alloys were in as-quenched state and after heat treatment with or without magnetic field. The morphology of researched coatings was different : amorphous and crystal. The suggested mechanism of the influence of coating is connected with appearance of anisotropic pseudo - uniaxial stresses in a plane of ribbon which are caused by anisotropic arrangement of coating elements in surface of ribbons.
