Electrically-induced strain and polarization studies of the (1-x)Pb(Mg1/3Nb2/3)O3-PbZrO3 crystalline solutions have been done. Dielectric constants with temperature were investigated for 0$leq$x$leq$0.95. With increasing PbZrO3 content the transition maxima were found to move to higher temperature region and DPT (Diffused Phase Transition) properties were decreased for x$leq$0.60. Phase transition between ferroelectric states and antiferroelectric states was confirmed for 0.93<x<0.95. Increase in the magnitude of the electrically-induced strains(S) and the degree of hysteresis were found with increasing PbArO3 contents. S was found to increase continuously with increasing PbZrO3 content, reaching a maximum value of ~1.3$ imes$10-3 for 0.4<x<0.95.
