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 …

Ferroelectrics carry a switchable spontaneous electric polarization. This polarization is
usually coupled to strain, making ferroelectrics good piezoelectrics. When coupled to …

The celebrated renaissance of the multiferroics family over the past ten years has also been
that of its most paradigmatic member, bismuth ferrite (BiFeO 3). Known since the 1960s to be …

The existence of domain walls, which separate regions of different polarization, can
influence the dielectric, piezoelectric, pyroelectric and electronic properties, of ferroelectric …

An insight into the analogies, state‐of‐the‐art technologies, concepts, and prospects under
the umbrella of perovskite materials (both inorganic–organic hybrid halide perovskites and …

Multiferroic materials have attracted much interest due to the unusual coexistence of
ferroelectric and (anti-) ferromagnetic ground states in a single compound. They offer an …

Taking a historical perspective, we provide a brief overview of the first-principles modeling of
ferroelectric perovskite oxides over the past 30 years. We emphasize how the work done by …

Competition between ground states at phase boundaries can lead to significant changes in
properties under stimuli, particularly when these ground states have different crystal …

Topological structures in multiferroic materials have recently received considerable attention
because of their potential use as nanoscale functional elements. Their reduced size in …
