The evolution of switching polarization (P-r(s)) suppression, in Pb(Zr,Ti)O-3 films, induced by two different electric treatments is addressed in terms of the nonlinear dielectric response. The ac electric field dependence of dielectric permittivity was collected at different fatigue states and the Rayleigh law was used to interpret the fatigue dependence of the nonlinear response. This approach has enabled us to distinguish between two fatigue stares induced by the different electric treatments.
