| Abstract | The complete high-order perturbation formulas based on a two-mechanism [i.e., crystal-field (CF) and charge-transfer (CT) mechanisms, the latter is neglected in the widely-used CF theory] model for the spin-Hamiltonian (SH) parameters (g factors g(//), g(perpendicular to) and the hyperfine structure constants A(//), A(perpendicular to)) of d(9) ions in tetragonal symmetry with the ground state vertical bar d(x2-y2)> are established. These formulas are used to the calculations of SH parameters for the tetragonal Cu2+ centers in trigonal CsCdCl3 and CSMgCl3 crystals. Form the calculations, these SH parameters are reasonably explained and the tetragonal distortions of the Cu2+ centers due to Jahn-Teller effect in both crystals are obtained. The results (including the tetragonal distortion and the relative importance of CT mechanism) are discussed. (C) 2009 Elsevier B.V. All rights reserved. |
