A systematic study of the effects of Co substitution on the crystal structure and magnetic anisotropy of Y/sub 2/Fe/sub 14-//sub x/Co/sub x/B and Nd/sub 2/Fe/sub 14-//sub x/Co/sub x/B has been carried out in order to clarify the different roles and contributions to the anisotropy of both rare earth and transition metals. The substitution of Co leads to an enhancement of the Curie temperature in both series of compounds. The Co has been found to provide a planar anisotropy which is larger than that of the axial anisotropy of Fe. A marked site preference has been observed. Two distinct contributions of the Co to the anisotropy have been observed.
