Abstract

PURPOSE:To form arbitrary magnetic anisotropy in the plane of an amorphous magnetic alloy readily by introducing crystallization areas locally to said alloy. CONSTITUTION:Crystallization areas 2, 2'... are introduced to a material 1 which is an amorphous magnetic alloy in the direction at a right angle to the direction where the formation of its anisotropy is desired, by adding a plurality of linear distortions or heat in parallel thereto by the irradiation of electron beams, the irradiation of laser light, pressing with a knife edge, or other suitable methods or further by such means as annealing this. Easy magnetic anisotropic axes are formed in the arrow directions of the material 1 by the tension effect. Or the easy magnetic anisotropic axes in the arrow directions are formed by introducing areas 2, 2' concentrically to the material. It is preferable that the depth of the introduction of the crystallization areas is <=1/2 the thickness of the material 1.
