Abstract

Pyroelectric and dielectric properties and switching of ferroelectric PLZT ceramics have been studied in the range 290–470 K. The effect of γ-irradiation on pyroelectric coefficient, dielectric permittivity and rate of Barkhausen jumps sequence at polarization switching of PLZT ceramics is found to be most pronounced at phase transition.
