Mechanically compatible and electrically neutral domain walls in tetragonal, orthorhombic, and rhombohedral ferroelectric phases of ${\text{BaTiO}}_{3}$ are systematically investigated in the framework of the phenomenological Ginzburg-Landau-Devonshire model with parameters of J. Hlinka and P. Marton, Phys. Rev. B 74, 104104 (2006). Polarization and strain profiles within domain walls are calculated …
