摘要：

A cross-sectional high-resolution electron microscopy study was performed on (010)/(100)-oriented ferroelectric Bi3.25La0.75Ti3O12 (BLT) films. Using Bragg filtering, curved, irregular, and nanoscale 90degrees domain configurations were observed. The weak ferroelastic strain of 0.024% suggests a negligible polarization clamping of 90degreesa-b domains under bipolar electric field and an easy 90degrees switching of the polar a axis in the ab plane. In addition, antiphase boundaries were characterized. A negligible contribution of 90degreesa-b domains to the fatigue of BLT is proposed. (C) 2004 American Institute of Physics.
