Abstract
When a slurryobtained by dispersing a rare-earth-compound powder in a solvent is applied to sintered magnet bodies, and dried to remove the solvent in the slurry and cause the surfaces of the sintered magnet bodies to be coated with the powder, and the sintered magnet bodies coated with the powder are heat treated to cause the rare-earth element to be absorbed by the sintered magnet bodies, the sintered magnet bodies having had the slurry applied thereto are dried by being irradiated with near infrared radiation having a wavelength of 0.8-5 μm, to remove the solvent in the slurry, and cause the surfaces of the sintered magnet bodies to be coated with the powder. As a result, the rare-earth-compound powder can be uniformly and efficiently applied to the surfaces of the sintered magnet bodies.
