摘要：
The study of the complex dielectric function of LiNbO3:Fe (LBN:Fe) single crystals reveals the presence of well-defined low-frequency relaxations associated to Fe ions. This relaxation process is very sensitive to iron doping, heat treatment, and sample temperature. As far as we know, this is the first observation of this relaxation process in LBN associated to the iron ion. The investigation of these properties is very important in view of applications of LBN:Fe as a photorefractive material and especially in recent holographic volume storage, optical image, and signal processing.
