a dielectric constants response and (b) piezoelectric coefficients response. The peak amplitude and frequency of the AC electric fields for de-poling were 4 kV/cm and 1 Hz, respectively. Variations in the properties were measured at each cycle. The results show that the poled crystals were clearly depoled after AC electric fields were applied.
