Functional Domain Walls in Multiferroic Materials - from symmetry to quantitative properties (FDWMM)

The main aim of the present project is to analyze local tensorial properties of selected DWs (profiles of primary and secondary order parameters, strains, stresses, susceptibilities, etc.) and to disentangle the different mechanisms that contribute to their spatial dependencies. We will use a broad spectrum of theoretical methods (a novel symmetry approach, Landau-Ginzburg-Devonshire theory, effective medium approach) and simulation techniques (Phase-Field, ab-initio based machine learning, molecular dynamics, etc.) and experimental techniques (pyrocurrent-, SHG-, elasticity- measurements ), which solely are available through close collaboration between the two research groups (Department of Dielectrics, Institute of Physics of the Czech Academy of Sciences, CZ & Physics of Functional Materials, Faculty of Physics, University of Vienna, Austria) and the international collaboration partners.
