• The local structure of Fe doped LiNbO3 crystal fabricated by the Czochralski technique was examined by X-ray absorption fine structure analysis. We found that Fe3+ was dominant in LiNbO3:Fe (0.1%), and that Fe atoms occupied Li atomic sites in LiNbO3 crystal. Also, we found that the local structure around Fe atoms is highly disordered so that the higher shells with structural periodicity disappeared.
