摘要：

Domains in 0.9Pb(Zn1/3Nb2/3)O-3 - 0.1PbTiO(3) or "PZN-PT' single crystals under the application of electric field were investigated with an optical microscope. The dynamic response of the domains was studied under an electric field on PZNPT crystals is reported. In this study, electric field applied along [001]. The domain formation with the changing temperature showed the successive phase transitions from cubic to tetragonal and then to rhombohedral with decreasing temperature. The room temperature configuration showed the co-existence of both rhombohedral and tetragonal domains. Under the given experimental conditions we found that a single domain state could be induced only in the tetragonal state. Even though the temperature was lowered to - 100 degrees C, complete transformation to the rhombohedral state was not observed.
