摘要：
There is disclosed a permanent magnet comprising a sintered alloy composed of rare earth elements (R), boron and iron. This permanent magnet is substantially constituted by 2-phase systems, i.e. a ferromagnetic Fe-rich phase (Nd.sub.2 Fe.sub.14 B) and a nonmagnetic R-rich phase (Nd.sub.97 Fe.sub.3), and has BH.sub.max of more than 38.0 MGOe.
