Magnetic skyrmions are particle-like nanometre-sized spin textures of topological origin
found in several magnetic materials, and are characterized by a long lifetime. Skyrmions …

MXenes, generally referring to two-dimensional (2D) transition-metal carbides, nitrides, and
carbonitrides, have received tremendous attention since the first report in 2011. Extensive …

Ever since its discovery the notion of Berry phase has permeated through all branches of
physics. Over the past three decades it was gradually realized that the Berry phase of the …

BiFeO3 is perhaps the only material that is both magnetic and a strong ferroelectric at room
temperature. As a result, it has had an impact on the field of multiferroics that is comparable …

Reversible protonic ceramic electrochemical cells (R‐PCECs) are emerging as ideal
devices for highly efficient energy conversion (generating electricity) and storage (producing …

Understanding the magnetic interactions is of fundamental importance in condensed-matter
physics as well as in the application of spintronic devices. In the past 13 years, the …

Multiferroic materials, which show simultaneous ferroelectric and magnetic ordering, exhibit
unusual physical properties—and in turn promise new device applications—as a result of …

Multiferroic magnetoelectric materials, which simultaneously exhibit ferroelectricity and
ferromagnetism, have recently stimulated a sharply increasing number of research activities …

The B-site substituted perovskite oxides A 2 B′ B ″O 6 have in the recent decades gained
an increasing amount of interest due to their various interesting properties and possible …

Abstract Two-dimensional (2D) materials such as graphene and transition-metal
dichalcogenides reveal the electronic phases that emerge when a bulk crystal is reduced to …
