Abstract
The results from studies of domain borders by the optical and acoustic topography methods in LiNbO3:Fe samples are presented. The formation of Fe ion concentration gradients, a change in the refractive index, and a gradient of the photoinduced field and parameters of acoustic waves near the domain borders were observed. It is shown that main reason for the distortion of crystalline structure parameters is the formation of photoinductive field gradients of spatially separated Fe2+ and Fe3+ ions.
