Domain structure, which is often quite complicated, is known to play an important role in the macroscopic piezoelectric and dielectric response in ferroelectric perovskite oxides. In the seminar I will present results of our recent effort to separate different domain-structure-related contributions to the permittivity from each other. For this sake, we use a combination of simulations and calculations within the framework of the Ginzburg-Landau-Devonshire model as parametrized for the prototypic ferroelectric compound BaTiO3.
