我们研究了在相同条件下沿三个晶轴（[001]，[110]和[111]）通过分子束外延生长的Co/Pd超晶格的单轴磁各向异性。我们的测量结果明确地表明，各向异性能量随晶体取向的大系统变化完全是由各向异性的体积贡献差异引起的。我们发现垂直界面的各向异性与外延取向无关（0.63 +/- 0.05 erg/cm2），因此是Co/Pd界面的固有性质。
We have studied the uniaxial magnetic anisotropy of Co/Pd superlattices grown under identical conditions by molecular-beam epitaxy along the three crystal axes: [001], [110], and [111]. Our measurements unambiguously demonstrate that the large systematic variations of the anisotropy energy with crystal orientation result solely from differences in the volume contribution to the anisotropy. We find the perpendicular interface anisotropy to be independent of the epitaxial orientation (0.63 +/- 0.05 erg/cm2), and hence to be an intrinsic property of the Co/Pd interface.
