PROBLEM TO BE SOLVED: To obtain magnetic fine particles of multilayer structure and a method of manufacturing the same, and to improve a magnetic multilayer fine particle dispersion medium formed by the use of the magnetic fine particles in high-frequency magnetic field absorption properties and magneto-optical properties. SOLUTION: A multilayer magnetic fine particle is composed of a fine particle serving as a center nucleus and a single-layered or multilayered coating layer covering the center nucleus. A ferromagnetic layer, formed by plating ferrite, is made to serve as the coating layer for the formation of magnetic multilayer fine particles, the magnetic multilayer fine particles are dispersed in a binder, the binder, where the magnetic multilayere fine particles are dispersed, is molded into a magnetic multilayer fine particle medium. |
