In this study, the real and imaginary parts of the complex permittivity of PZT ferroelectric thin films are studied in the frequency range of 100 Hz – 100 MHz. The permittivity is well fitted by the Cole-Cole model. The variation of the relaxation time with temperature is described by the Arrhenius law and an activation energy of 0.38 eV is found.
