Abstract
The object of the present invention relates to ferrite particles for bonded magnets and a resin composition for bonded magnets which is capable of obtaining a bonded magnet molded product having a good magnetic force and a magnetic waveform as well as high iHc and Hk by injection molding. The present invention aims at providing a bonded magnet molded product using the ferrite particles and the resin composition. The aforementioned object of the present invention can be achieved by ferrite particles for bonded magnets which have a crystal distortion of not more than 0.14 as measured by XRD, and an average particle diameter of not less than 1.30 μm as measured by Fisher method; a resin composition for bonded magnets; and a molded product obtained by injection-molding the resin composition.
