Rare earth sintered magnet and method for production thereof

A rare earth sintered magnet which has a main phase of an R 2 T 14 Q type tetragonal compound (R represents at least one rare earth element, T represents at least one transition metal comprising Fe, and Q represents boron and/or carbon) and a grain boundary phase surrounding the main phase, characterized in that the R 2 T 14 Q type tetragonal compound in the main phase comprises, as essential elements, Cr substituting for a part of Fe and carbon substituting for a part of boron, and the main phase has a carbon concentration higher than that of the grain boundary phase; and a method for producing the rare earth sintered magnet. The rare earth sintered magnet is excellent in corrosion resistance and sintering characteristics.
