Abstract
In this paper, amorphous Fe-B (AFB) submicrometer particles were coated with ferrite by the ferrite plating method. The AFB/ferrite composite particles (AFC particles) showed higher resistivity than AFB particles. The polymer composites of AFC particles also showed higher resistivity than those of AFB particles, which lead to suppression of electric conduction and eddy current loss in highly-filled polymer composites. Therefore, AFC particles using ferrite plating method were effective for the increase in volume fraction of metallic particles with a size of submicrometer, and for suppressing eddy current loss.
