Abstract
The temperature dependence of the electro-optic coefficient of Pb 1 - x La x (Zr y ,Ti 1 - y ) 1 - y/4 O 3 ceramics with x= 0.09 and y= 0.65 was investigated in the field cooling and the zero field cooling run conditions. The electro-optic coefficient in the field cooling run increased continuously until 150 K, but in the zero field cooling run decreased below 230 K. The discrepancy was attributed to the freezing of ferroelectric domains and to the resultant insensitivity to the external electric field.
