Abstract Domains and domain walls are a fundamental property of interest in ferroelectrics,
magnetism, ferroelastics, superconductors, and multiferroic materials. Unlike magnetic Bloch …

Unlike ideal 180 ferroelectric walls that are a unit cell wide (∼ 0.5 nm)⁠, real walls in
ferroelectrics have been reported to be many nanometers wide (1–10 nm). Using scanning …

We report changes in the Raman spectra at ferroelectric domain walls in near-stoichiometric
LiNbO3 and stoichiometric LiTaO3. We find a decrease of intensity for the regular bulk …

Ferroelectric materials such as lithium niobate and lithium tantalate show a non-linear
hysteresis behaviour, which may be explained by dynamical system analysis. The behaviour …

A model of a ferroelectric crystal in terms of a one-dimensional array of ferroelectric slab
domains is treated theoretically for the dynamics of the “array of domains.” Two approaches …

Abstract Through the Landau–Ginzburg–Devonshire mean field theory, the equation
governing the behavior of the polarization field in ferroelectric material is derived …

Ferroelectric materials, such as lithium niobate, show interesting non-linear hysteresis
behavior that can be explained by a dynamical system analysis. By using variational …

In the framework of a simple model of a one-dimensional array of a ferroelectric slab of
domains, the polarization with time and space is explained by the Klein-Gordon equation. A …

The nonlinear hysteresis behavior in ferroelectric materials, such as lithium tantalate and
lithium niobate, may be explained by dynamical systems analysis. In a previous work, the …
