Temperature Dependence of Electric Field Induced Strain in PLZT 9/65/35 Ceramics

Abstract

In this study, leadbased ferroelectric ceramics Pb 0.91 La 0.09 Zr 0.65 Ti 0.35 O 3 PLZT (9/65/35) were fabricated by solid solution method. The electrical and mechanical properties were measured by modified Michelson interferometer and Sawyer-Tower circuit to investigate electric field induced strain and polarization (s-P-E) of PLZT (9/65/35) at 30-70 °C. The induced strain and polarization were changed when the temperature was increased indicating the change of spontaneous polarization inside the ferroelectric materials.
