Abstract. The temperature dependence of the permittivity ε and the pyrocurrent I of bulk ceramic samples with the composition Pb(Zr0.51Ti0.49)O3 + 0.1 wt% Cr2O3 is studied in this work. The residual polarization P, the relaxation time τ and the activation energy ΔE were calculated from the pyrocurrent curves. The temperature dependence of the permittivity of thin films prepared by laser evaporation in vacuum is studied.
