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 …

Complex oxides are record holder materials for many phenomena, including ferroelectricity,
piezoelectricity, superconductivity and multiferroicity. Complex oxides often have competing …

Gauss's law dictates that the net electric field inside a conductor in electrostatic equilibrium
is zero by effective charge screening; free carriers within a metal eliminate internal dipoles …

The metal–insulator transition and the intriguing physical properties of rare-earth perovskite
nickelates have attracted considerable attention in recent years. Nonetheless, a complete …

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

The weak interlayer coupling in van der Waals (vdW) magnets has confined their application
to two dimensional (2D) spintronic devices. Here, we demonstrate that the interlayer …

Vertically aligned nanocomposite thin films with ordered two phases, grown epitaxially on
substrates, have attracted tremendous interest in the past decade. These unique …

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 …

BiFeO3-based heterostructures have attracted much attention for potential applications due
to their room-temperature multiferroic properties, proper band gaps and ultrahigh …

Exchange bias and magnetic proximity effects are two novel phenomena that are in the
limelight because of their fundamental and technological importance. Since both …
