FIELD: electronics. SUBSTANCE: process is meant for manufacture of thin magnetic films with preset properties for storages. Two magnetic layers separated by nonmagnetic layer are deposited on dielectric substrate and upper layer is subjected to chemical etching. As result coercive force of this layer increases and magnetic inhomogneities are formed simultaneously. Magnetostatic interaction of magnetic leakage fields from inhomogeneities with magnetization of lower layer leads to rise of its coercive force. EFFECT: increased coercive force of lower layer. 1 dwg
