改性PbTiO3铁电畴的极化反转和反转率的计算
POLARIZING SWITCH AND CALCULATION OF POLARIZING SWITCH OF FERROELECTRIC DOMAINS IN MIDIFIED PbTiO3
【摘要】 对改性PbTiO3铁电材料畴结构的研究表明,90°畴的取向及极化反转同极化电场有关。用x射线衍射法测算的晶体而网密度指数可以定量地描述90°畴的取向并山此计算出90°畴的极化反转率。
【Abstract】 The domain structure of modified PbTiO3 ferroelectric material was investigated. The results indicate that the orientation and the polarizing swtch of 90° domains are related to the polarizing field. The density factor of crystalline plane P（hk1）, measured by XRD method, can be used to quantitatively describe the orientation of domains and to calculate the polarizing switch ratio of 90 ° dlmains.
