计算表明，实验发现的Co/Pd界面各向异性的令人惊讶的“取向独立性”是该系统所表现出的精确应变程度的偶然结果，并且通常不是预期的。这些结论得到了实验与我们对各向异性大小的电子结构计算之间的良好一致性的支持，并且与简单的基于对称性的理论的结果密切相关，其中应变的影响很明显
Calculations show that the surprising «orientation independence» of the Co/Pd interface anisotropy found experimentally is an accidental consequence of the precise degree of strain exhibited by this system and is not generally expected. The conclusions are supported by the good agreement between experiment and our electronic structure calculations for the anisotropy magnitude, and by the close correlation with the results of a simple symmetry-based theory in which the effects of strain are clear
