shows the temperature dependence of the ferroelectric properties for the PLZT 7.6/70/30 composition. The values of saturation polarization (Ps), remnant polarization (Pr), and coercive field (Ec) decreased with the increase of the temperature. It is interesting to note that a double-loop-like behavior, which is a characteristic of an induced ferroelectric–antiferroelectric transformation, can be observed when temperature rises above 54 °C. The plausible reason could be attributed to a coexistence of the AFE and FE states for PLZT 7.6/70/30 composition
