<P>PROBLEM TO BE SOLVED: To provide magnetic particulates each comprising a multilayer structure and its manufacturing method, and to improve magneto-optical characteristics, etc. by forming a magnetic multilayer particulate dispersing medium by using the magnetic particulates. <P>SOLUTION: Magnetic multilayer particulates, each comprising a ferromagnetic layer formed by ferrite plating on a covering layer which has particulates forming a central nucleus and a single or a plurality of covering layers, are manufactured. The magnetic particulates are dispersed into a binder and molded, to form a dispersing element of the magnetic multilayer particulates that is a magneto-optical effect material. <P>COPYRIGHT: (C)2004,JPO |
