The evolution of the dynamic hysteresis with electrical field amplitude (E) and frequency (f) in the ferroelectric BaTiO₃ (BTO) single crystal films prepared by pulsed laser deposition (PLD) has been investigated systematically. A noticeable transition from the low-frequency behavior to the high-frequency one was confirmed by observing the obtained hysteresis loops and the change of the physical properties. In addition, the analysis of the theoretical model shows that the frequency dependence of domain motion is the cause of the dynamic hysteresis loop scaling behavior.

外延铁电 BaTiO ₃薄膜动态滞后的标度行为

已经系统地研究了通过脉冲激光沉积 (PLD) 制备的铁电 BaTiO ₃ (BTO) 单晶薄膜中电场幅度 ( E ) 和频率 ( f )动态滞后的演变。通过观察获得的磁滞回线和物理特性的变化，确认了从低频行为到高频行为的明显转变。此外，理论模型的分析表明，域运动的频率依赖性是动态磁滞回线缩放行为的原因。
