A dielectric study of the X/65/35 lanthanum-modified lead zirconate-titanate series

Abstract
The occurrence (or not) of a ferroelectric phase transition and the field induced ferroelectric to relaxor states transition has been studied through dielectric susceptibility and pyroelectric current experiments in the x/65/35 PLZT series (x=5 to 12). The results are qualitatively interpreted using random field theory principles.
