Abstract
Co-57 Mossbauer emission spectra of undoped and Fe or Mg melt-doped LiNbO3;
single crystals show substantial amounts of the nucleogenic Fe3+ charge st
ate (*Fe3+) which was generated as an after-effect of the electron-capture
of Co-57(2+). The proportion of *Fe3+ is markedly dependent on the Mg conte
nt and on the stoichiometry of the sample. Electron trapping is described w
ithin the model of competing accepters. The capabilities of the model are i
nvestigated in defect structure analysis and charge trapping studies of LiN
bO3.
