采用分子束外延技术在(1 1 1)和(1 0 0)单晶衬底上制备了Rh/Co/Rh三明治。在两种取向下，Rh基层上的Co层均以面心立方结构外延生长。Co层厚度在0.35~10 nm之间的(111)取向薄膜的垂直磁各向异性大于(100)取向的薄膜，特别是在1 nm左右。在Rh/Co/Rh夹层中，两种取向之间的各向异性差比在Pt/Co/Pt中小得多，这对应于Rh/Co系统较小的晶格失配。
Rh/Co/Rh sandwiches were prepared by MBE method on MgO(1 1 1) and (1 0 0) single-crystal substrates. For both orientations, the Co layers grow epitaxially with FCC structure on the Rh base layers. The (1 1 1) oriented films with Co layer thickness between 0.35 and 10 nm exhibit perpendicular magnetic anisotropy larger than (1 0 0) films especially at around 1 nm. The difference in the anisotropy between the two orientations is much smaller in Rh/Co/Rh sandwiches than in Pt/Co/Pt, corresponding to smaller lattice misfit of Rh/Co system.
