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 …

The burgeoning field of anion engineering in oxide‐based compounds aims to tune physical
properties by incorporating additional anions of different size, electronegativity, and charge …

Abstract The Jahn–Teller effect, in which electronic configurations with energetically
degenerate orbitals induce lattice distortions to lift this degeneracy, has a key role in many …

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 …

Understanding the local cation order in the crystal structure and its correlation with
electrochemical performances has advanced the development of high‐energy Mn‐rich …

Large disorder effects due to size differences between A-site R 3+(R= L a, P r, N d, S m) and
M 2+(M= C a, S r, B a) cations have been found in magnetoresistive (R 0.7 M 0.3) Mn O 3 …

Basic mechanisms controlling orbital order and orbital fluctuations in transition metal oxides
are discussed. The lattice driven classical orbital picture, eg like in manganites LaMnO 3, is …

Experimental, phenomenological, and theoretical analyses are given of the dependence on
strain of the ferromagnetic Tc of the colossal magnetoresistance CMR rare earth manganese …

We report a dc magnetization study of the critical phenomena in a high-quality single crystal
of the double-exchange ferromagnet La 0.7 Sr 0.3 MnO 3. We have determined the critical …

The Van Hove singularity (VHS) provides a paradigm for the study of the role of peaks in the
density of states (dos) on electronic properties. More importantly, it appears to play a major …
