Title:

METHOD FOR PRODUCING RARE-EARTH MAGNET

Document Type and Number:

WIPO Patent Application WO/2012/036294

Kind Code:

A1

Abstract:

[Problem] To provide a method for producing an anisotropic rare-earth magnet that can be enhanced in coercive force without adding a large quantity of rare metals such as Dy and Tb. [Solution] A method for producing a rare-earth magnet, including a step of bringing a compact, which is obtained by hot-working a sintered compact having a rare-earth magnet composition to provide anisotropy thereto, into contact with a low-melting-point alloy melt containing a rare-earth element.
