文摘
A phenomenological model was modified for dynamic hysteresis loops of hard ferroelectric PbZr1−xTixO3 (PZT). The comparison with experimental results showed that the modified model can reproduce polarization versus an electric field. A predicted hysteresis loss of hard ferroelectric PZT was formulated and estimated. The calculations showed an increase in hysteresis loss with a decrease of frequency at a 40-kV/cm electric field amplitude.
