Recently, ferroelectric tunnel junctions (FTJs) have attracted considerable attention for
potential applications in next‐generation memories, owing to attractive advantages such as …

Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of
orders of magnitude, and are widely observed in condensed-matter systems. This article …

CARBON nanotubes are predicted to have interesting mechanical properties—in particular,
high stiffness and axial strength—as a result of their seamless cylindrical graphitic structure1 …

Multiferroic magnetoelectrics are materials that are both ferromagnetic and ferroelectric in
the same phase. As a result, they have a spontaneous magnetization that can be switched …

Computer memory that is non-volatile and therefore able to retain its information even when
switched off enables computers that do not need to be booted up. One of the technologies …

The study of the manganese oxides, widely known as manganites, that exhibit the “colossal”
magnetoresistance effect is among the main areas of research within the area of strongly …

A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

The magnetocaloric effect describes the change in temperature of a magnetic material under
adiabatic conditions through the application or removal of an external magnetic field. This …

Mixed-valence manganese oxides (R1-χAχ) MnO3 (R= rare-earth cation, A= alkali or
alkaline earth cation), with a structure similar to that of perovskite CaTiO3, exhibit a rich …
