Field-induced Strains and Polarization Switching Mechanisms in $Pb(Mg_{1/3}Nb_{2/3})O_3-PbZrO_3$ Ceramics

ABSTRACT

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$0.60. Phase transition between ferroelectric states and antiferroelectric states was confirmed for 0.93$times$10-3 for 0.4
