Abstract

Ferroelectric performance for ferroelectric material of PbZr_xTi_1-xO₃ changes by heat treatment. We investigated the relation between physical properties, crystal structure and ferroelectric performance of the sample before and after various heat treatment. The crystal structure was determined by Rietveld analysis using neutron powder diffraction data. From the results, Pr of PbZr_xTi_1-xO₃ (x=0.40,0.45), and Ec and Tc of PbZr_xTi_1-xO₃ (x=0.40) increase by annealing at high Po₂. The ferroelectric performance was affected by changing the defect of oxygen.
