Ab initio study of double perovskites Ba2DySbO6

AIP Conference Proceedings, 2016
First principle study of the electronic band structure of Ba2DySbO6 synthesied by the solid state reaction technique have been performed within the framework of density function theory using WIEN2K. It has been shown in the absence of electron-electron interaction (U=0), BaDySO6 behaves like a half-metal.

Defect processes in orthorhombic LnBaCo2O5.5 double perovskites

Physical Chemistry Chemical Physics, 2011
Static atomistic simulations based on the Born model were used to investigate intrinsic defect processes in orthorhombic LnBaCo(2)O(5.5) (Ln = Y, La, Pr, Nd, Sm, Gd, Dy, Ho, Er, and Yb) double perovskites. It was found that Ln/Ba antisite disorder is the lowest energy defect reaction, with the large Ln cations giving rise to smaller antisite energies ...

LaSrMnCoO6: a new cubic double perovskite oxide

Journal of Solid State Chemistry, 2003
Abstract Single-phase polycrystalline powder samples of the double perovskite oxide LaSrMnCoO6 were synthesized by the Pechini (citrate-gel) technique. The structural, magnetic and electrical properties of the obtained powders were investigated by X-ray diffraction, electron microscopy, dc magnetization, ac susceptibility and dc resistivity ...

Vacancy-Ordered Double Perovskites

2020
The related vacancy-ordered double perovskites can be produced by replacing one B-site cation with a vacancy, resulting in a material with the \(\text {A}_2\text {BX}_6\) formula (or \(\text {A}_2\text {B}\square {}\text {X}_6\), where \(\square \) is a vacancy).
