Abstract
PROBLEM:To provide a production method of an anisotropic rare earth magnet capable of being enhanced in coercivity without adding a large amount of a rare metal such as Dy and Tb.MEANS FOR RESOLUTION:A production method of a rare earth magnet, comprising a step of bringing a compact obtained by applying hot working to impart anisotropy to a sintered body having a rare earth magnet composition into contact with a low-melting-point alloy melt containing a rare earth element.
