| Abstract: | This paper deals with the microstructure and magnetism for Nd 4Fe 77.5 B 18.5 nanocrystalline alloy by various experiments. The results indicate that the phase Nd 2Fe 14 B in this alloy may be metastable and distributes in Fe 3B grains. The exchange coupling interaction between Nd 2Fe 14 B and Fe 3B is the origin of the permanent properties of this alloy. |
