ABSTRACT:
A composition for resin-bonded magnets. The resin-bonded magnets using the composition of the resin have excellent service lives in industry, excellent magnetic characteristics and excellent mechanical strength. A composition for resin-bonded magnets contains a magnetic powder and resin binder. The magnetic powder contains a transition metal element as one of the constituent elements. The binder contains, as the major ingredient, a thermosetting resin containing an organic peroxide and having radical-polymerization reactivity, and is further incorporated with an N-oxyl compound. Also disclosed is a composition including magnetic powder, thermosetting resin having radical-polymerization reactivity and organic oxide as the major ingredients, and a resin-bonded magnet using the same.
