Abstract: PMN-PZT ceramic composition near the morphotropic phase boundary (MPB) with formula 0.1Pb (Mg1/3Nb2/3)O3 -0.9Pb(Zr0.5Ti0.5)O3 or 0.1PMN-0.9PZT is prepared by a conventional mixed-oxide method. The hysteresis properties are investigated as a function of poling field strength by a simple Sawyer-Tower circuit. It is found that the shape of the hysteresis loops does not change significantly with the poling field strength. However, the remanent polarization (Pr) and spontaneous polarization (Ps) values increase with increasing the poling field strength because an increase in a DC poling field magnitude re-orients more domains with the poling field direction, while the coercive field (Ec) is relatively constant and its value indicates a minimum field required to cancel all the polarizations.
