摘要：

NMR results are used to evaluate the spin-orbit contribution to the magnetic anisotropy of Co atoms at individual Co sites in RCo5 compounds. The easy c-axis Co anisotropy of RCo5 compounds is found to arise from the (2c) sites, while the (3g) 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(Co1-xFex)5 compounds and also to estimate anisotropy parameters at individual sites in some structures related to the RCo5 phase. © 1979 The American Physical Society.
