| Abstract | In this paper, we calculate the EPR parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to)) of rare earth ion Sm3+ in fluoride crystals KY3F10 and LiYF4 from the perturbation formulas of EPR parameters for a 4f(5) ion in tetragonal symmetry. In these formulas, the crystal-field J-mixing of the first and second excited-state multiplets H-6(7/2) and H-6(9/2) into the ground state multiplet H-6(5/2), the mixtures among the states with the same J value via spin-orbit coupling interaction and the interactions between the ground Kramers doublet Gamma(gamma) and the same irreducible representation as Gamma(gamma) in other 11 Kramers doublets Gamma(chi) within H-6(J) (J = 5/2, 7/2, 9/2) states via crystal-field and orbital angular momentum (or hyperfine structure) are considered. The calculated results (which are in agreement with the observed values) are discussed. (C) Published by Elsevier B.V. |
