摘要
本文测量了铁电液晶SmC 相在交变电场作用下展开螺旋结构的临界场与温度和频率的变化关系 ,在实验过程中观察到了滞后现象和重入现象。另外给出了高频临界的理论计算结果、理论和实验符合得较好。
In this paper,we measured the dpendence of the critical field on temperature and frequency.During experment,we imvestiated the hysterseis phenomenom.In addition we ealculated the critical field on the base of the general cspression for the system's free energy.The theoretical result fit well the esperimental data.
