Ferroelectric Bloch walls and ferroelectric Ising lines — Vilma Stepkova, Pavel Marton, and •Jiri Hlinka — Institute of Physics, Czech Acad. Sci., Prague

In this contribution we would like to address geometry and properties of plausible topological defects chiral ferroelectric domain walls of perovskite ferroelectrics, in particular linear defects analogous to dislocations or disclination lines known from liquid crystals. We will present our investigations of the properties of such one dimensional objects obtained within the Ginzburg-Landau-Devonshire theory using phase-field simulations.
