Domain wall splitting and creation of the fine domain structure Academic Article uri icon


  • The study of the movement of the paraelectric-ferroelectric interphase boundary in (Ba,Sr)TiO3 with concentration change is provided in the framework of the mean-field theory. The analytical solution for the parameters of motion of the interphase boundary is applied to the calculations of the splitting of domain walls in (Ba,Sr)TiO3 for different concentrations of Sr. 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.
