The emancipation of ferroelectricity [PDF]
Nature Materials, 2007 Contrary to bulk materials, high-resolution microscopy of ultra-thin ferroelectric films finds only a weak coupling of polarization down to unit-cell dimensions. The established theoretical picture can be resurrected by the inclusion of epitaxial strain effects.

Ferroelectricity in Doped Incipient Ferroelectrics
AIP Conference Proceedings, 2002We consider the quantum properties of mixed incipient ferroelectrics with small concentrations of ferroelectricity inducing ions such as KTa1−xNbxO3. We show that the nonuniform strong intra‐band electron ‐ phonon interaction leads to the localization of virtual conduction band electrons around the Nb ions and to the off ‐center displacements of these ...

Journal of the American Ceramic Society, 2005
The reorientation of defect dipoles and the drift of free charge carriers are the most prominent microscopic mechanisms under discussion to provoke the aging effect in ferroelectrics. These two mechanisms are contrasted taking into account the influence of grain boundaries in a polycrystalline material.

Principles and Applications of Ferroelectrics and Related Materials
, 1977The book develops the modern theory of ferroelectricity in terms of soft modes and lattice dynamics and also describes modern techniques of measurement, including X-ray, optic, and neutron scattering, infra-red absorption, and magnetic resonance.

Molecular Design Principles for Ferroelectrics: Ferroelectrochemistry.
Journal of the American Chemical Society, 2020Ferroelectricity, which refers to the switching property of polarizations in a material, has been an important topic in material science. To be ferroelectrics, crystals must crystallize in one of the ten polar point groups: 1 (C1), 2 (C2), m (Cs), mm2 ...

Science, 1951
Ferroelectricity is a very general phenomenon. Yet it is possible to divide it into three main groups with essentially three different mechanisms: the order-disorder of hydrogen bonds, the trigger effect of nonspherical radicals, and the 4π/3 catastrophe due to high electronic polarizabilities.

Why Are There so Few Magnetic Ferroelectrics
, 2000Multiferroic magnetoelectrics are materials that are both ferromagnetic and ferroelectric in the same phase. As a result, they have a spontaneous magnetization that can be switched by an applied magnetic field, a spontaneous polarization that can be ...
