Research output: Contribution to journalArticlepeer-review


The hydrostatic-pressure-induced kinetics of paraelectric-ferroelectric phase transitions is considered on the basis of the time-dependent Ginzburg-Landau theory. The exact solution describing the interphase boundary at first-order ferroelectric phase transitions is used for analyzing the movement of the interphase boundary under the influence of hydrostatic pressure. Temperature and pressure dependences of the interphase boundary width and velocity are calculated by using the experimental data in BaTiO3. Power laws of the temperature and pressure behavior of the interface velocity v=v(T-Tc) and v=v(p-c) are found. The pressure hysteresis is calculated.
