Ferroelectric Domain Wall Memristor [PDF]
Advanced Functional Materials, 2020 AbstractA domain wall‐enabled memristor is created, in thin film lithium niobate capacitors, which shows up to twelve orders of magnitude variation in resistance. Such dramatic changes are caused by the injection of strongly inclined conducting ferroelectric domain walls, which provide conduits for current flow between electrodes. Varying the magnitude

Ferroelectric Domain Wall Injection
Advanced Materials, 2014 Ferroelectric domain wall injection has been demonstrated by engineering of thelocal electric field, using focused ion beam milled defects in thin single crystal lamellae of KTiOPO4 (KTP).

Domain wall diffusion and domain wall softening
Journal of Physics: Condensed Matter, 2003A number of experimental and computational studies of materials have shown that transport rates in domain walls may significantly differ from those in the bulk. One possible explanation for enhanced transport in a domain wall is that the domain wall is elastically soft with respect to the bulk. We investigate the softening of a ferroelastic domain wall

Physical Review D, 1996
Domain walls form naturally in the early Universe whenever a discrete symmetry is spontaneously broken at some phase transition. When each vacuum is populated equally, it is well known that the domain wall network comes to dominate the energy density of the Universe and causes excessive anisotropy in the cosmic microwave background.

Domain-wall structure and domain-wall strain
Journal of Applied Physics, 2003Stresses and strains within domain walls are important for understanding the interaction of domain walls with point defects, and the surface structure of the domain walls. Unfortunately, attempts to determine these properties of the domain wall by diffraction or other methods fail because of the low resolution of the technique.

Physical Review E, 1994
Dynamical properties of the domain walls (DW's) in the light beams propagating in nonlinear optical fibers are considered. In the bimodal fiber, the DW, as it was recently demonstrated numerically, separates two domains with different circular polarizations. This DW is found here in an approxiate analytical form. Next, it is demonstrated that the fiber'

Technological evolution and revolution are both driven by the discovery of new functionalities, new materials and the design of yet smaller, faster, and more energy-efficient components. Progress is being made at a breathtaking pace, stimulated by the rapidly growing demand for more powerful and readily available information technology.

DOMAIN WALLS IN HIGHER DIMENSIONS
International Journal of Modern Physics D, 1998Thick domain walls with nonvanishing stress component in the direction perpendicular to the plain of the wall are considered. Their exact solutions are obtained in the background of a five-dimensional spacetime. There may be both expanding and collapsing walls.

Anisotropy of Domain Wall Resistance
Physical Review Letters, 2000The resistive effect of domain walls in FePd films with perpendicular anisotropy was studied experimentally as a function of field and temperature. The films were grown directly on MgO substrates, which induces an unusual virgin magnetic configuration composed of 60 nm wide parallel stripe domains. This allowed us to carry out the first measurements of

Domain Walls and Wall Structure
1991The concept of a magnetic domain wall is as fundamental to the domain theory as the domains themselves. The original formulation of what we now call a Bloch Wall assumed an infinite sample, an energy of both exchange and anisotropy and recognized that the lowest energy would be when the demagnetizing field across the wall was zero.
