ABSTRACT
The X-band electron paramagnetic resonance study of Er-doped Bi4Ge3O12 single crystals at 5 K is reported. The spectra have been attributed to Er3+ ions in the Bi3+ site, confirming the assumed trigonal site symmetry of Er3+ in previous crystal-field analysis. A detailed study of the measured g-factor values indicates that corrections to the existing crystal-field parameters Bnm should be performed. It is suggested that corrections to the sixth-rank parameters are particularly important, in agreement with spin-correlated crystal-field (SCCF) effects for Er3+.
