The stress and temperature dependence of three different lead zirconate titanate ceramics have been measured at 48 h and 1 month after poling. The data were fit to a modified Rayleigh law in which a negative quadratic stress term accounts for a saturation of the domain wall contributions at higher stress. The relative changes to the fitting parameters can be explained by the materials possessing differences in the concentration of orientable defect dipoles, but with similar distributions of relaxation time constants.
