The changes in domain structure with compositions, dc bais and ac field for (001)-oriented PMN-xPT crystals was investigated using polarized optical microscopy. The miniature polar domains exhibits an increasing degree of self-assembly with increasing x from polar nanodomains for x<0.25, to fine crosshatched domains near the morphotrophic phase boundary (MPB). It was observed that an applied dc electrical bias change morphology from fine crosshatched to thin-aligned striationlike domains. An ac electric field applied to the crosshatched domains result in a irregular domain wall oscillations/relaxations.
