Pressure-induced migration of ferroelectric interfaces

Research output: Contribution to journal › Conference article › peer-review

Abstract

The study of the migration of the first-order paraelectric-ferroelectric interfaces in BaTiO₃ under the hydrostatic pressure is provided in the framework of the time-dependent Ginzburg-Landau theory. The analytical solution describing the interphase boundary is applied for the calculations of its width and velocity at different pressures. The calculations are based on the experimental data for BaTiO₃. The parameters of the power law of the temperature and pressure dependences of the interface velocity under the temperature and pressure were obtained. Using the BaTiO₃ example we illustrate the ability of the suggested approach in the description of the kinetics of the first-order ferroelectric phase transition in perovskites.
