| 中文摘要 | The single-phase nanocrystalline Pr2Fe14B magnets composed of cubic-shaped and irregular-shaped grains is built. The magnetic hysteresis loops are simulated by micromagnetism finite element method. The remanence, coercivity and maximum energy product decrease with deteriorated grain alignment. Attributed to strong intergrain exchange coupling (IGEC), the variation of magnetic properties with alignment degree is significantly affected by the average grain size in nanocrystalline magnets. The investigation shows the increase of coercivity with improved grain alignment in nanocrystalline magnets, which is completely different from the phenomena in sintered magnets. |
