HIGH SPECIFIC RESISTANCE AND LOW LOSS COMPOSITE SOFT MAGNETIC MATERIAL, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a high specific resistance and low loss composite soft magnetic material. SOLUTION: An Mg-containing oxide coated soft magnetic particle consists of an Fe-based soft magnetic metal particle and an Mg-containing oxide coating film with which the surface of the soft magnetic metal particle is coated. The plurality of Mg-containing oxide coated soft magnetic particles are combined through a grain boundary layer composed of a composite compound of one of a silicon compound and the Mg-containing oxide coating film, low-melting point glass and the Mg-containing oxide coating film and a metal oxide and the Mg-containing oxide coating film.
