While cation order–disorder transitions have been achieved in a wide range of materials
and provide crucial effects in various physical and chemical properties, anion analogues are …

In electronic applications, good dielectric permittivity material has huge potential in the
capacitive energy storage devices. Herein, in the present work the dielectric study of …

In this review, we describe different families of metastable materials, some of them with
relevant technological applications, which can be stabilized at moderate pressures 2–3.5 …

Metal-to-insulator transitions (MITs), which are achieved in 3d-band correlated transitional
metal oxides, trigger abrupt variations in electrical, optical, and/or magnetic properties …

Here, for the first time, we report the stabilization of high entropy quadruple perovskites of
general formula with a typical structural feature of 1: 3 ordering of A-site cations. The …

A-site-ordered AA′ 3B4O12 quadruple perovskites (with twelve-fold coordinated A and
square-planar coordinated A′ sites) were discovered in 1967. Since then, there have been …

Electronic structure calculations based on density functional theory (DFT) within the
generalized gradient approximation (GGA) and GGA+ U for manganite cuprate compound …

A-site-ordered quadruple perovskites RMn7O12 with R= Sm, Eu, Gd, and Tb were
synthesized at high pressure and high temperature (6 GPa and∼ 1570 K), and their …

The magnetic properties of double perovskite La 2 MnCoO 6 (LCMO) by making a
composite with ordered double perovskite CaCu 3 Ti 4 O 12 (CCTO) have been …

Charge and orbital degrees of freedom determine properties of many materials, and are
central to many important phenomena. At high temperatures, thermal fluctuations overcome …
