| 简介 | In an R—Fe—B based rare-earth sintered magnet according to the present invention, at a depth of 20 μm under the surface of its magnet body, crystal grains of an R2Fe14B type compound have an (RL1-xRHx)2Fe14B (where 0.2≦x≦0.75) layer with a thickness of 1 nm to 2 μm in their outer periphery. In this case, the light rare-earth element RL is at least one of Nd and Pr, and the heavy rare-earth element RH is at least one element selected from the group consisting of Dy, Ho and Tb. | ||
