Extrinsic contributions in a nonuniform ferroic sample: Dielectric, piezoelectric and elastic
P. Mokry, A. Kopal, J. Fousek
The contribution Delta_epsilon of extremely small motions of domain walls to small-signal permittivity of a multidomain ferroelectric sample has been a research issue for many year…

On the extrinsic piezoelectricity
A. Kopal, P. Mokry, J. Fousek +1
This work presents a continuation of our last paper, concerning the theory of the response of an antiparallel domain structure in a plate-like electroded sample to external electri…

Displacements of 180-degree domain walls in electroded ferroelectric single crystals: the effect of surface layers on restoring force
A. Kopal, P. Mokry, J. Fousek +1
Macroscopic properties of ferroelectric samples, including those in form of thin films, are, to large extent, influenced by their domain structure. In this paper the free energy is…
