Domain boundary contributions to the dielectric response — •Pavel Marton, Antonin Klic, Ivan Rychetsky, Petr Ondrejkovic, and Jiri Hlinka — Institute of Physics, Czech Acad. Sci., Prague

Importance of domain boundaries for application-related high-response ferroelectric perovskite oxides is widely accepted. Recent developments of the domain-engineering techniques allows to acquire domain sizes as small as only several tens of nanometers. Then the domain boundaries become true functional part with interesting properties, which significantly influence the behaviour of the material as a whole. In this contributions we investigate 180- and 90-degree layered domain structures within the Ginzburg-Landau-Devonshire model.
