Crystal structure of Ba2InTaO6 as determined by the Rietveld refinement

Investigation on the electronic structure, optical, elastic, mechanical, thermodynamic and thermoelectric properties of wide band gap semiconductor double perovskite Ba2InTaO6

In the present paper, double perovskite Ba₂InTaO₆ was investigated in terms of its structural, electronic, optical, elastic, mechanical, thermodynamic and thermoelectric properties using density-functional theory (DFT).

The changes in the Ge₃O₁₀conformation and coordination environment of the three nonequivalent sites of metal cations within the structures of CaY₂Ge₃O₁₀, CaPr₂Ge₃O₁₀and CaLa₂Ge₃O₁₀.

Symmetry-mode analysis of the phase transitions in SrLaZnRuO6and SrLaMgRuO6ordered double perovskites

The crystal structures of double perovskites SrLaMRuO6(M= Zn and Mg) have been studied using X-ray and neutron diffraction data. Both compounds have monoclinic structure at room temperature with space groupP21/n. A first-order structural phase transitionP21/n→R{\overline 3} has been observed in SrLaZnRuO6and SrLaMgRuO6, at about 800 and 500 K, respectively, with the two phases coexisting in a temperature interval of 150 K. The temperature- and tolerance-factor-dependent phase diagram of the SrLnMRuO6(Ln = La, Nd and Pr;M= Zn, Co, Cu, Mg and Ni) family shows two different phase transition sequences depending on theA-site cation. The structures of the title compounds at room and high temperatures have been analyzed using the symmetry-mode decomposition approach.
