几种实验方法来测量铁电电滞回线，并提取极化值进行了比较，薄膜具有显着的损失和不同幅度的极化。该分析允许确定最合适的频率范围和技术，以提取具有低偏振和高泄漏的材料中的反射偏振的可靠值。实例包括多铁性YMnO（3）和Bi（0.9）La（0.1）NiMnO（6）薄膜。(C)2011年美国物理学会。[doi：10.1063/1.3555098]
Several experimental methods to measure ferroelectric hysteresis loops and to extract polarization values are compared for thin films with significant losses and different magnitudes of polarization. The analysis allows the determination of the most appropriate frequency range and technique to extract reliable values of the remanent polarization in materials with low polarization and high leakage. Examples include multiferroic YMnO(3) and Bi(0.9)La(0.1)NiMnO(6) thin films. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3555098]
