The magnetocrystalline anisotropy of the Y 2 Co 17 compound is caused by Co atoms. The anisotropy is calculated within the point charge model in the crystal field approach. The shielding effects of band electrons are taken into account. The calculations are extended to Y 2 (Co 1− x Mn x ) 17 and Gd 2 (Co 1− x Mn x ) 17 with 0 ≦ x ≦ 0.3. The results of the calculations fit the experimental anisotropy data, describe well the changes of the anisotropy versus temperature and Mn concentration, and are consistent with conclusions concerning the local Co anisotropy drawn from NMR data.
