Abstract

PURPOSE: To improve magnetic characteristics, particularly retention power by forming a resin layer on a non-magnetic material layer provided on the surface of a magnetic compound, the volume ratio of the resin to the particles constituting the non-magnetic material layer being less than 50%.
CONSTITUTION: The surface of powder constituting the non-magnetic material layer provided on the surface of magnetic compound particle of RMz (R: one or more rare earth elements; M: Co or alloy comprised mainly of Co; and z: 6.5...8.8) is magnetically hardened by a resin or non-magnetic metal of an amount of less than 50%. In this way, magnetic characteristics, particularly retention power is improved.
