| 中文摘要 | The octahedral (FeO6)9- and tetrahedral (FeO4)5- clusters in yttrium gallium garnet (YGG): Fe3+ system are investigated based on the 252 252 complete energy matrices for d5 configuration ions in trigonal and tetragonal ligand fields, moreover, the EPR and optical spectra are made unified calculation. The results indicate that the defect structures around Fe3+ centres display expansion effects at different temperatures 4.2 and 295 K, and which are close to those in YIG garnet, respectively. Simultaneously, the defect structure parameters for Fe3+ centres in YGG are determined, and the relationship between the defect structure and the temperature has been discussed. |
