| 简介 | The present invention provides a multiphase magnet, which has a small grain diameter and thus has superior magnetic properties, by : preparing a powder mixture by mixing a first powder having the composition Re1-Fe-B and a second powder having the composition Re2-Fe-B; and producing an anisotropic bulk magnet by subjecting the powder mixture to anisotropic bulking, wherein the rare earth metal included in Re1 differs in kind and/or amount from the rare earth metal included in Re2. | ||
