Investigation of dielectric properties of Fe/PZT and Co/PZT thin films

PbZr0.5Ti0.5O3 ceramic material, which has ferroelectric properties, attracts great attention from researchers due to its electrical and electromechanical properties. In this study, Fe and Co materials with ferromagnetic properties were coated separately on the ferroelectric PbZr0.5Ti0.5O3 (PZT) ceramic material by vacuum evaporation technique. The variation of dielectric properties such as the real and imaginary parts of dielectric constant, loss tangent, cole-cole diagram of the prepared thin films with frequency was examined. The real and imaginary parts of dielectric constant, loss tangent, cole-cole diagram of pure PZT, Fe-coated PZT and Co-coated PZT thin films were measured with an impedance analyzer as a function of frequency in the range of high frequency (1 MHz – 3 GHz) at room temperature.
