We consider the nanoscale electronic phase separation in a wide class of different
materials, mostly in strongly correlated electron systems. The phase separation turns out to …

Oxidoreductases play crucial roles in electron transfer during biological redox reactions.
These reactions are not exclusive to protein-based biocatalysts; nano-size (< 100 nm), fine …

Here we report on the impact of reducing the crystalline size on the structural and magnetic
properties of γ-Fe2O3 maghemite nanoparticles. A set of polycrystalline specimens with …

The metal–insulator transition driven by electronic correlations is one of the most
fundamental concepts in condensed matter. In mixed-valence compounds, this transition is …

The nature of the Verwey transition occurring at TV≈ 125 K in magnetite (Fe3O4) has been
an outstanding problem over many decades. A complex low temperature electronic order …

A review of progress in understanding the Verwey transition in magnetite (Fe3O4) over the
past decade is presented. This electronic and structural transition at TV≈ 125 K was …

The magnetic and electronic structures of Fe4O5 have been investigated at ambient and
high pressures via a combination of representation analysis, density functional theory (DFT+ …

Functional oxides whose physicochemical properties may be reversibly changed at
standard conditions are potential candidates for the use in next‐generation nanoelectronic …

CuO6 octahedra usually show elongated distortion, leading to active dx 2− y2 orbitals and
planar exchange interactions, while compressed CuO6 octahedra with active d 3 z 2− r 2 …

In the lacunar spinels, with the formula AB4X8, transition-metal ions form tightly bound B4
clusters resulting in exotic physical properties such as the stabilization of Néel-type skyrmion …
