Abstract

The Ginzburg-Devonshire phenomenological approach is used to define the correlation between temperature and electric field magnitudes required to keep permanent values of permittivity of ferroelectrics in rather broad range of operating temperatures. The existence of a crossover of the electric field dependencies for ε at different temperatures is demonstrated theoretically. It makes it possible to establish the upper limit of electrical field strength necessary to provide the thermal stability of ferroelectric devices. Theoretical results have been confirmed experimentally with (Ba,Sr) TiO3 thin film measurements.
