OXIDATION-RESISTANT RARE EARTH BASED MAGNET POWDER AND METHOD FOR PRODUCTION THEREOF, COMPOUND FOR RARE EARTH BASED BONDED MAGNET, RARE EARTH BASED BONDED MAGNET AND METHOD FOR PRODUCTION THEREOF

摘要

An oxidation-resistant rare earth based magnet powder, characterized in that it has a layer containing a pigment as a primary component adhered onto its surface; a method for producing the magnet powder; a compound for a rare earth based bonded magnet; and a rare earth based bonded magnet and a method for the production thereof. The magnet powder is useful for producing a rare earth based bonded magnet which is excellent in the resistance to oxidation and also exhibits high magnetic characteristics.
