| 简介 |
According to one embodiment, a permanent magnet is provided with a sintered body having a composition represented by R(FepMqCurCo1-p-q-r)zOw (where, R is at least one element selected from rare-earth elements, M is at least one element selected from Ti, Zr and Hf, and p, q, r, z and w are numbers satisfying 0.25≦p≦0.6, 0.005≦q≦0.1, 0.01≦r≦0.1, 4≦z≦9 and 0.005≦w≦0.6 in terms of atomic ratio). The sintered body has therein aggregates of oxides containing the element R dispersed substantially uniformly. |
