Zusammenfassung:PROBLEM TO BE SOLVED: To provide a bonded-magnet composition that has excellent fluidity and includes rare earth-iron-nitrogen based magnetic powder, ferrite magnetic powder, and a resin binder, and a bonded magnet using the same. SOLUTION: The bonded-magnet composition includes rare earth-iron-nitrogen based magnetic powder with a Th2Zn17-type crystal structure, ferrite magnetic powder, and a resin binder. The circularity coefficient of the rare earth-iron-nitrogen based magnetic powder is ≥0.6. COPYRIGHT: (C)2008,JPO&INPIT
