通过压电力显微镜对溶胶凝胶法制备的0.8PbTiO3-0.2Bi(Mg0.5Ti0.5)O3铁电薄膜电畴结构进行研究。结果表明，薄膜中铁电相为主相，面内极化的a畴和离面极化的c畴同时存在于铁电纳米晶粒中。在针尖极化电场的作用下，薄膜晶粒内的电畴取向发生变化，180°电畴翻转分为两步90°畴转实现，最终完成c-a-c的电畴转变。温度的变化影响畴转的过程，温度越高越有利于畴转，这与有效电场的增大有关。

In ferroelectrics, the presence of domain structures and switchable polarization plays an important role in ferroelectric performance and the design of future electronic devices. Understanding domain behaviors is crucial for ferroelectrics promising applications, particularly in nonvolatile memory, microwave ceramics, electromechanical sensors and actuators. As a convenient, nondestructive and high-resolution technique, the piezoresponse force microscopy (PFM) provides a powerful method for observing domain structures and their dynamic behavior at the micron and nanometer scales. In this work, PFM has been used to study the domain structures and their dynamic behavior of 0.8PbTiO3-0.2Bi(Mg0.5Ti0.5)O3 thin film. Both the a domain and the c domain coexist in the ferroelectric thin film nanometer grains. Under the tip-bias-induced electric field, the domain switching follows the two 90° steps of 180° domain switching, showing the domain polarization change from c to a to c. A remarkable effect of temperature on the domain configurations and domain dynamic response in 0.8PbTiO3-0.2Bi(Mg0.5Ti0.5)O3 thin film was found by PFM. Under the tip bias voltage of 5 V, domain evolution was more rapid with a higher temperature at 70 ℃. The surface charge is related with c domain polarization. At high temperature, the surface charge induced effective electric filed increases, allowing for the easier domain motion.
