FERRITE PARTICLE POWDER FOR BONDED MAGNETS, RESIN COMPOSITION FOR BONDED MAGNETS, AND MOLDED ARTICLE USING SAME

摘要

The purpose of the present invention is to provide a ferrite magnetic powder for bonded magnets and a resin composition for bonded magnets, with which it is possible to obtain a bonded-magnet molded article having good magnetic characteristics and magnetic waveforms for injection molding, as well as high iHc and Hk. Another purpose of the present invention is to provide a bonded-magnet molded article using said ferrite particle powder and said composition. Said purposes are achieved by a ferrite particle powder for bonded magnets, characterized in that the crystal strain measured by XRD is 0.14 or less and the average particle size according to the Fischer method is 1.30 μm or more, and also achieved by a resin composition for bonded magnets, and a molded article obtained by injection molding.
