Abstract
An anisotropic rare earth sintered magnet represented by the formula (RZr)(FeCO)(MM)where R is at least one element selected from rare earth elements and Sm is essential; Mis at least one of V, Cr, Mn, Ni, Cu, Zn, Ga, Al, and Si; Mis at least one of Ti, Nb, Mo, Hf, Ta, and W; and x, y, a, b, and c each satisfy certain conditions. The anisotropic rare earth sintered magnet includes 80% by volume or more of a main phase composed of a compound of a ThMntype crystal, the main phase having an average crystal grain size of 1 μm or more, and containing an R-rich phase and an R(Fe,Co)phase in a grain boundary portion. A method for producing the anisotropic rare earth sintered magnet is also described.
