COMPOSITE MAGNETIC MATERIAL, MANUFACTURING METHOD THEREOF, AND RAW MATERIAL SET OF COMPOSITE MAGNETIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a magnetic material which is arranged by use of &egr;-FeOand enables the rise in residual magnetic flux density and the increase in coercive force.SOLUTION: A composite magnetic material comprises: oxidation iron particles 5 containing &egr;-FeO3 and metal iron 4; and rare earth-iron based particles 1 formed from a compound including a rare earth element and iron. The rare earth-iron based particles 1 are made larger than the oxidation iron particles 5 in average particle diameter. The rare earth-iron based particles 1 are made larger than the oxidation iron particles 5 in volume fraction.
