Ferroelectric domain walls have emerged as a new type of interface in which the dynamic
characteristics of ferroelectricity introduce the element of spatial mobility, allowing real-time …

The manipulation of magnetic properties by an electric field in magnetoelectric multiferroic
materials has driven significant research activity, with the goal of realizing their …

Ferroelectric and ferroelastic domain walls are 2D topological defects with thicknesses
approaching the unit cell level. When this spatial confinement is combined with observations …

Materials with a coexistence of magnetic and ferroelectric order—multiferroics—provide an
efficient route for the control of magnetism by electric fields. The study of multiferroics dates …

Abstract Bismuth ferrite (BiFeO 3, BFO) as one of the few single-phase room-temperature
multiferroics, has aroused ever-increasing enthusiasm in research communities during the …

Ferroelectric domain walls naturally form at nanoscale interfaces of polar order leading to
electronic properties distinct from the bulk that can also be electrically programmed. These …

The charged domain wall is an ultrathin (typically nanosized) interface between two
domains; it carries bound charge owing to a change of normal component of spontaneous …

Ferroelectric domain walls hold great promise as functional two-dimensional materials
because of their unusual electronic properties. Particularly intriguing are the so-called …

Achieving a periodic domain structure in ferroelectric materials to tailor the macroscopic
properties or realize new functions has always been a hot topic. However, methods to …

We present an overview of the current interest in non-collinear magnetism in multiferroic
perovskite crystals. We first describe the different microscopic mechanisms giving rise to the …
