The dielectric constant-voltage curves and polarization hysteresis loops of BST thin films with different thicknesses were investigated.
6Sr0.4TiO3（BST）薄膜，研究了不同膜厚的BST薄膜的介电偏压特性曲线和电滞回线。
The relationships between the dielectric constant, the dielectric loss and frequency of PLCT ( x) ceramics, and the hysteresis loops of PLCT ( x) thin films were measured.

The Computerized System for Dynamic Measuring Dielectric Hysteresis and Electrical Field Induced Strain Simultaneously
电诱应变与电滞回线微机控制同步测量系统
The results also show that the density and the dielectric properties of ceramics are related to the crystallite size. The hysteresis loop also changes after doping.
研究结果还表明，陶瓷的致密度、介电性能均与陶瓷晶粒尺寸大小有关，掺杂后陶瓷的电滞回线均发生变化，Sb3+掺杂使矫顽场和剩余极化减小并解释了原因。
