This review stands in the larger framework of functional materials by focussing on
heterostructures of rare-earth nickelates, described by the chemical formula RNiO 3 where R …

The electronic structure of transition metal oxides featuring correlated electrons can be
rationalized within the Zaanen-Sawatzky-Allen framework. Following a brief description of …

This article reviews static and dynamic interfacial effects in magnetism, focusing on
interfacially driven magnetic effects and phenomena associated with spin-orbit coupling and …

Finding new collective electronic states in materials is one of the fundamental goals of
condensed matter physics. Atomic-scale superlattices formed from transition metal oxides …

In an effort to scale down electronic devices to atomic dimensions, the use of transition-metal
oxides may provide advantages over conventional semiconductors. Their high carrier …

Complex transition metal oxides have played a central role in the study of magnetic
materials, serving as model systems for explorations of fundamental exchange interactions …

We present a theory describing the local electronic properties of the perovskite rare-earth
nickelates—materials which have negative charge transfer energies, strong O 2 p–Ni 3 d …

Resistances that exceed the Mott-Ioffe-Regel limit (known as bad metal behavior) and non-
Fermi liquid behavior are ubiquitous features of the normal state of many strongly correlated …

A combined analysis of x-ray absorption and resonant reflectivity data was used to obtain
the orbital polarization profiles of superlattices composed of four-unit-cell-thick layers of …

In rare earth nickelates (RENiO3), electron-lattice coupling drives a concurrent metal-to-
insulator and bond disproportionation phase transition whose microscopic origin has long …
