Figure 3

Electric polarization (P) versus electric field (E) hysteresis loops measured with a triangular ac electric field of various frequencies for (a) c-direction polarization of CRCA, (b,c) a- and c*-direction polarization of CBDC, (d) polarization normal to the Inline graphic plane of HPLN, and (e) c-direction polarization of ALAA. (f) A schematic waveform used for optimization in an endurance measurement mode.
