Temperature dependent switching mechanism of (Pb0.92La0.08)(Zr0.65Ti0.35)O3 investigated by small and large signal measurements

摘要

The transition region between the field induced ferroelectric and the ergodic phase in relaxornferroelectrics offers the possibility to study the switching behavior as a function of the increasingnrelaxor character of the system. Here, field dependent small and large signal measurements arenpresented. The results obtained at distinct temperatures below the transition temperature Tt fornu0002Pb0.92La0.08u0003u0002Zr0.65Ti0.35u0003O3 concerning Pu0002Eu0003, Su0002Eu0003, u000233u0002Eu0003, and d33u0002Eu0003 display a strong temperaturendependence. Analysis of the reversible and irreversible domain processes leads to the conclusionnthat switching occurs through an intermediate nanodomain state even in the ferroelectric regime.
