Divergence of dielectric permittivity near phase transition within ferroelectric domain boundaries
Original language description
Phase-field simulations based on Ginzburg-Landau-Devonshire model were utilised to demonstrate and quantify the enhancement of the dielectric permittivity of multidomain rhombohedral BaTiO3 crystal in the vicinity of the Bloch-type to Ising-type phase transition within 180° domain boundaries with {211} crystallographic orientation. The phase transition is driven by compressive mechanical stress applied in the plane perpendicular to the spontaneous polarisation direction. Simulations reveal a classical Curie-Weiss behaviour of the transverse component of dielectric permittivity, expected in the vicinity of a second-order phase transition.
