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 YMnO3 and Bi0.9La0.1NiMnO6 thin films.

These artifacts can be easily subtracted in DHM and DLCC methods, since Rs can be evaluated from the slope in the I(V) curve; the time shift caused by L also allows an easy estimate of L.
