Abstract
(1-x)PSN-xPLuN ceramics with single phase perovskite structure and rhombohedral symmetry at room temperature were prepared by solid-state reaction method. The influence of unaxial pressure (0-1500 bars) on dielectric properties of these compounds were studied. It is found that these materials are sensitive to external stress. This includes the shift of phase transitions, diffuseness of dielectric permittivity characteristics and the decrease of the thermal hysteresis of the permittivity and field-polarization hysteresis. These changes of properties could be connected with the change in domain structure, the elastic change of distances between ions and the change in defects density.
