初始磁化，退磁和磁粘度数据提出了烧结和熔融纺NdFeB在一定温度范围内。采用基于强畴壁钉钉的模型研究了各工况下运行中的能垒。温度对材料的磁化性能影响不大，而对材料的退磁过程影响很大。这似乎意味着在磁化和退磁过程中有非常不同的机制在起作用。>
Initial magnetization, demagnetization, and magnetic viscosity data are presented for sintered and melt-spun NdFeB over a range of temperatures. A model based on strong domain wall pinning is used to investigate the energy barriers in operation in each case. Temperature is observed to have little effect on magnetization of the material, whereas the demagnetization process is found to be greatly affected. This seems to imply that very different mechanisms are at work in the magnetization and demagnetization processes. >
