Abstract
The present invention relates to ferrite particles for bonded magnets and a resin composition for bonded magnets which exhibit a good moldability, in particular, a good mechanical strength even when rapidly quenched upon injection-cooling, and is capable of producing a bonded magnet molded product having excellent magnetic properties, as well as a bonded magnet molded product such as a magnet roll using the ferrite particles and the resin composition. There are provided ferrite particles for bonded magnets which comprise phosphorus adsorbed and/or incorporated in ferrite, in which a content of the phosphorus in the ferrite is 120 to 5000 mg/kg (0.012 to 0.50% by weight) in terms of P; a resin composition for bonded magnets; and a magnet roll.
