COMPOSITE MAGNETIC MATERIAL AND METHOD FOR MANUFACTURING SAME

摘要

A composite magnetic material containing: a metal magnetic powder comprising a plurality of metal magnetic particles; and mica as an inorganic insulator present between the metal magnetic particles. The Fe content of the mica is no greater than 15 wt% in terms of Fe­2O3 in relation to 100 wt% of the mica in total. To create this composite magnetic material, first, the metal magnetic powder and mica are mixed and dispersed between each other, and a powder mixture is prepared. Then, the powder mixture is compact-molded and a compact is formed. The compact is then heat-treated.
