    摘要: The object of the present invention is to provide a powder core and method for making the same that is equipped with insulative coating having superior heat resistance, with the coating making it possible to adequately restrict the flow of eddy currents between particles.The powder core is equipped with a plurality of compound magnetic particles bonded to each other. Each of said plurality of composite magnetic particles includes: a metal magnetic particle 10; an insulative lower layer coating 20 surrounding a surface 10a of said metal magnetic particle 10; an upper layer coating 30 surrounding said lower layer coating 20 and containing silicon; and dispersed particles 50 containing a metal oxide compound and disposed in said lower layer coating 20 and/or said upper layer coating 30. A mean particle diameter R of the dispersed particles 50 meets the condition 10 nm

    摘要: The object of the present invention is to provide a method for manufacturing a soft magnetic material, a soft magnetic material, a method for manufacturing a P/M soft magnetic material, and a P/M soft magnetic material which achieve the desired magnetic properties. In the method for manufacturing the soft magnetic material of the present invention, there is a first heat treatment step (step S3) in which a metal magnetic particle 10, which has iron as its main component, is heat treated to a temperature of 900 degrees C. or greater and less than the melting point of metal magnetic particle 10. After the first heat treatment step (step S3), there is a step for forming a plurality of composite magnetic particles 30 which are metal magnetic particles 10 surrounded by an insulation covering 20 (step S6).
