Abstract
Visualization of as-grown domain patterns and local polarization reversal were carried out in ferroelectric single crystals Pb5Ge 3O11 and LiNbO3 using scanning probe microscopy. The piezoresponse force microscopy (PFM) was used for domain imaging. The problem of PFM background signal smearing the domain contrast was solved by special mathematical treatment resulting in clear PFM images. This analysis was applied for extracting the field dependence of the size of domains produced by local polarization reversal in Pb5Ge3O 11. The strong effect of abnormal polarization reversal resulting in appearance of the domains with polarization anti-parallel to locally applied field was demonstrated in LiNbO3.
