摘要：

Formation and evolution of the bands with nanodomain structure in front of the moving domain wall were studied in proton exchanged LiNbO3 in field range. The width of the nanodomain bands grew with field increasing. For switching in constant field three types of domain structure evolution were studied: 1) continuous growth of hexagon domains at 21.0 kV/mm, 2) formation and growth of wide domain wall at 21.5 kV/mm, 3) growth of micro-and nanodomain ensembles at 22.0 kV/mm. Discrete switching being the origin of obtained effects is caused by retardation of depolarization field screening in crystal with dielectric surface layer.
