摘要	The spin-Hamiltonian parameters g factors g(parallel to), gperpendicular to and hyperfine structure parameters A(parallel to) and A(perpendicular to) for Er3+ (Er-167) in CaWO4 and SrWO4 are theoretically studied by using the perturbation formulas of the spin-Hamiltonian parameters for a 4f(11) ion in tetragonal symmetry. In these formulas, the contributions to the spin-Hamiltonian parameters arising from the second-order perturbation terms and the admixture of various states are considered. The crystal-field parameters for the tetragonally distorted tetrahedra are calculated from the superposition model and the local structural data of the impurity Er 3, ions at the host Ca2+ and Sr2+ sites. The theoretical parameters are in agreement with the experimental values. The validity of the results is discussed. (C) 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
