Theoretical Interpretation of the EPR Parameters for Dy3+ Ion in LuPO4 Crystal

  • Hui-Ning Dong EMAIL logo , Hui-Ping Du , Shao-Yi Wu and Peng Li

Based on the superposition model, in this paper the EPR parameters gII and g of Dy3+, and the hyperfine structure constants AII and A of 161Dy3+ and 163Dy3+ in LuPO4 crystal are calculated by perturbation formulas from the crystal-field theory. In the calculations, the contributions of various admixtures and interactions such as J-mixing, mixtures among states with the same J-value, twoorder perturbation, covalency as well as local lattice relaxation are considered. The calculated results agree reasonably with the observed values
