Abstract
The study of the movement of the paraelectric-ferroelectric interphase boundary in (Ba,Sr)TiO3 (BST) and Pb(Zr,Ti)O3 (PZT) perovskites with concentration change and BST in constant magnetic fields is provided in the framework of the mean-field theory. The analytical solution for the parameters of motion of the interphase boundary is applied for the calculations of the splitting of domain walls in BST with the magnetic field tuning for different concentrations of Sr. The wetting of domain walls in PZT is shown for some concentrations of Ti. The calculations are based on the experimental data for the Curie-Weiss constant and for the parameters of the Landau-Ginzburg expression for the free energy.
