| 中文摘要 | The optical spectrum and the local defect Structure of tetrahedral (FeO(4))(5-) clusters are investigated in yttrium gallium garnet (YGG) and lutetium gallium garnet (LGG) crystals by means of the 252 x 252 complete energy matrices for d(5) configuration ions in tetragonal ligand field. The results show that the local defect structures around tetrahedral Fe(3+) centers display an expansion effect. Simultaneously, the (FeO(4))5- Clusters in the two different crystals have very similar local structures, which are close to those in YIG garnet crystal. Finally the relative curves of the zero-field splitting energies Delta E(1) and Delta E(2) in the ground state (6)A(1) varying with the structure parameter theta are plotted. (C) 2009 Elsevier B.V.
