Abstract
The effect of uniaxial pressure (0–1000 bars) applied parallel or perpendicular to the ac electric field on electric properties of soft PZT ceramics has been investigated. It was found that uniaxial pressure significantly influences these properties. With increasing pressure the peak intensity in the ε(T) curve decreases, becomes diffuse and shifts to a higher temperature, dielectric hysteresis is reduced, and dielectric dispersion decreases. It was shown that the application of pressure perpendicular to the electric poling direction improves the ferroelectric properties. It was concluded, that applied uniaxial pressure or increasing Ti-ion concentration in PZT system induces similar effects. The results were discussed in term of Cochran soft-mode model and domain switching under influence of pressure.
