Ferroelectric domains, domain walls, symmetry and thermodynamic models — •Jiri Hlinka — Institute of Physics, Czech Acad. Sci., Prague, Czechia

Properties and applications of the materials with ferroelectric or other kind of ferroic domains separated by domain walls continue to stimulate our desire to image, model and understand these ultimate nanoscale interfaces in more and more details. We aim to present here only the most general theoretical concepts that can be useful in related physics and materials science activities. In this tutorial presentation, also aimed to facilitate the most recent achievements presented at the DPG meeting, we intend to cover the subject mostly from the phenomenological point of view, relying on the symmetry constraints and Ginzburg-Landau theory arguments.

Keywords: Ferroic domains; domain walls; ferroelectrics
