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.
