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 …

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

Ferroelectric materials, because of their robust spontaneous electrical polarization, are
widely used in various applications. Recent advances in modelling, synthesis and …

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 …

Among the different types of multiferroic compounds, bismuth ferrite (BiFeO 3; BFO) stands
out because it is perhaps the only one being simultaneously magnetic and strongly …

Ferroelectric domain walls are atomically sharp topological defects that separate regions of
uniform polarization. The discovery of electrical conductivity in specific types of walls gave …

Mobile charged defects, accumulated in the domain-wall region to screen polarization
charges, have been proposed as the origin of the electrical conductivity at domain walls in …

Over the last 30 years, the study of ferroelectric oxides has been revolutionized by the
implementation of epitaxial‐thin‐film‐based studies, which have driven many advances in …

Domains in ferroelectrics were considered to be well understood by the middle of the last
century: They were generally rectilinear, and their walls were Ising-like. Their simplicity …

Ferroelectric materials have remained one of the major focal points of condensed matter
physics and materials science for over 50 years. In the last 20 years, the development of …
