| Title of Invention | RARE EARTH PERMANENT MAGNET |
|---|---|
| Abstract | A rare earth permanent magnet is in the form of a sintered magnet body having a composition R1 aR2 bTcAdFeOfMg wherein F and R2 are distributed such that their concentration increases on the average from the center toward the surface of the magnet body, and grain boundaries having concentration of R2/ (R1+R2) which is on the average higher than the concentration of R2 / (R1+R2) contained in primary phase grains of (R1,R2)2T14A tetragonal system form a three-dimensional network structure which is continuous from the magnet body surface to a depth of at least 10 μm. The invention provides R-Fe-B sintered magnets which exhibit a high coercive force. |
