研究了晶体 Dy2Fe14B 和 Nd2Fe14B 的 (001) 表面的电子结构，并通过第一性原理计算估计了稀土位点的晶体场参数。结果表明，表面的 Dy 或 Nd 离子表现出面内磁各向异性，可以成为磁化反转的成核位点。 (C) 2011 年美国物理研究所。 [号码：10.1063/1.3553935]
The electronic structures of a (001) surface of crystalline Dy2Fe14B and Nd2Fe14B have been studied and the crystal field parameters at the rare-earth sites have been estimated by using first principles calculations. It is shown that Dy or Nd ions at the surface exhibit an in-plane magnetic anisotropy and can be nucleation sites of magnetization reversal. (C) 2011 American Institute of Physics.
