Abstract
Polycrystalline Pb(ZrxTi1-x)O3 thick films have been prepared by spin-on and rapid sintering in a conventional oven. The remanent polarization and coercive field of a 80 µm thick film are studied versus the applied field. Modellings from the admittance curves and from a modified Mason circuit can explain that the weaker electromechanical characteristics of the PZT layer against the bulk material are due both to the porosity and to the existence of an inactive layer. A characterization by the beam method shows a good correlation between the theoretical and experimental resonance frequencies.
