核磁共振结果被用来评估R-Co5化合物中各个Co位的Co原子的自旋轨道对磁各向异性的贡献。RCo5化合物的易c轴Co各向异性是由(2c)位引起的，而(3g)位的贡献相对较小。利用各位各向异性参数计算了混合R(Co1−xFex)5化合物中各向异性随组成的变化，并估算了与R Co5相有关的某些结构中各位各向异性参数。
NMR results are used to evaluate the spin-orbit contribution to the magnetic anisotropy of Co atoms at individual Co sites in R Co 5 compounds. The easy c-axis Co anisotropy of R Co 5 compounds is found to arise from the (2 c) sites, while the (3 g) sites make a smaller opposing contribution. The anisotropy parameters of the individual sites are used to calculate the variation of anisotropy with composition in mixed R (Co 1− x Fe x) 5 compounds and also to estimate anisotropy parameters at individual sites in some structures related to the R Co 5 phase.
