Abstract

PURPOSE:To solve the technical difficulty in the formation and eliminate the need for addition of yoke materials, thereby fully obtaining anisotropic effect using a single magnet, by giving it a two-layer structure consisting of a radial anisotropic layer and an isotropic layer. CONSTITUTION:A melt consisting of material compounds is pressed into a ring cavity corresponding to the size of isotropic layer of a resin magnet at a condition lacking in a magnetic field and a ring member Li' having an isotropic property is formed. The isotropic ring member Li' is inserted in the cavity 11 and its mounting allows peripheral surface sides to have a space 12 so as to form a radial anisotropic layer. The melt consisting of the material compounds is pressed into the space 12 under conditions impressed by radial magnetic field and a resin magnet having a two-layer structure consisting of a radial anisotropic layer La and an isotropic layer Li is obtained by solidifying the above pressed melt. As isotropy is given to a region located at the opposite side of a magnetic face, a sufficient effect is obtained without using a yoke material in the case of magnetic treatment of the above region and the resultant magnetization through magnetic treatment becomes stronger and has a high magnetic flux density.
