Effect of compressive stress on dielectric and ferroelectric properties of 0.25PSN-0.75PLuN ceramics

The PSN-PLuN solid solutions have been prepared in the whole composition range for the first time. The dielectric, pyroelectric and hysteresis loops measurements of the 0.25PSN-0.75PLuN ceramics stress-free or under the stress (0-1.5 kbar) have been carried out. It is found that compressive stress shifts the phase transformation and decrease the field-polarization hysteresis. These effects can be mainly connected with the change in domain walls dynamics and with polarization switching under the action of stress.
