The relation between polarization P and electric eld E in the solid solutions (1 .. x)Pb(Sc1=2Ta1=2)O3-xPbZrO3(PST-PZ) was investigated with the successive antiferroelectric (AFE) - ferroelectric(FE) - paraelectric(PE) phase transition with heating in the range of PZ compositions x > 0:8. It was found that P{E hysteresis loops change from the double P{E loop to the single one, re ecting the phase transition from AFE to FE. For the switching behavior in the AFE phase, it was found that the electric eld dependence of the reciprocal switching time and the peak switching current which characterize the switching transient consists of two parts ; one is the linear part at the high-eld region and the other is the curved part at the low-eld region.
