摘要	The spin-Hamiltonian (SH) parameters (g factors g(//), g(perpendicular to) and hyperfine structure constants A(//), A(perpendicular to)) for Co(2+) ions at the trigonal Mg(2+) (I) and Mg(2+) (II) sites of RbMgF(3) crystal are calculated from the second-order perturbation formulas based on the cluster approach for 3d(7) ions in trigonal symmetry. From the calculations, it is found that the calculated SH parameters for Co(2+) ion at the Mg(2+) (I) site are in poor agreement with, but those for Co(2+) at the Mg(2+) (II) site are close to, the experimental values. Therefore, we suggest that Co(2+) in RbMgF(3) crystal substitutes for Mg(2+) (II) ion. The results are discussed.
