| 中文摘要 | From the perturbation formulas based on the cluster approach for 3d(7) ion in trigonal octahedral sites of crystals, the spin Hamiltonian parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to)) for Co2+ in calcite-type MCO3 (M = Co, Cd, Ca) crystals are calculated. In the calculations, for CoCO3 crystal, the structural data of pure crystal are used, whereas for the Co2+-doped CdCO3 and CaCO3 crystals, the local structural data caused by the impurity-induced local lattice relaxation are considered. The calculated results show good agreement with the observed values obtained from electron paramagnetic and antiferromagnetic resonance experiments. The difficulty shown in the previous paper related to the g(perpendicular to) value of CoCO3 obtained from the change of the g factor as a function of the crystallographic data (i.e., the unit cell parameters) a(0) and alpha(0) of pure MCO3 crystals is removed.
