中文摘要	The local lattice structure distortions for YAG and YGG systems doped with Cr3+ have been investigated by the d(3) configuration complete energy matrices which contain the Zeeman energy besides the electron-electron interaction, the trigonal crystal field as well as the spin-orbit coupling interaction. The local lattice structure parameters R and theta of (CrO6)(9-) complex are determined for Cr3+ in YAG and YGG systems, respectively. The calculated results show that the local lattice structures have expansion distortions, which almost tend to the same after distortions. Meanwhile, the EPR parameter D, g factors (g(parallel to), g(perpendicular to)) and optical spectrum of these systems have been interpreted uniformly by quantitative calculation. It is shown that the effect of the orbit reduction factor k on g factors (g(parallel to), g(perpendicular to)) cannot be ignored. (C) 2007 Elsevier Ltd. All rights reserved.
