| Abstract: | Nanocomposite permanent magnet exhibits excellent magnetic properties combining high coercivity of permanent magnetic phase with high saturation magnetization of soft magnetic phase. The advances in theory including exchange-coupling interaction between magnetic phases, coercivity mechanism and computer-aided micromagnetic simulation and the effects of components, element additions and fabrication technology on the microstructure and magnetic properties are reviewed in this article. Melt spinning is introduced in detail, which is believed to be the most valuable application method. |
