The impact of anion ordering on octahedra distortion and phase transitions in SrTaO2N and BaTaO2N
Published 2017-01-01In this work, we synthesized BaTaO2N and SrTaO2N using a two-step high temperature solid state reaction method and analysed the structural distortions, relative to the ideal cubic perovskite structure, according to group ...Open AccessArticle -
Multi-scale Structural Analysis of the A-site and Oxygen Deficient Perovskite Sr11Mo4O2
Published 2017-01-01The long range average crystal structure, as well as the short and medium range structural features, of the A-site deficient and oxygen deficient perovskite Sr11Mo4O23 have been determined. Rietveld refinement of synchrotron ...Open AccessArticle -
Thermal Expansion Behavior in TcO2. Towards breaking the Tc-Tc bond.
Published 2017-01-01The structure of TcO2 between 25 and 1000 °C has been determined in-situ using powder diffraction methods and is found to remain monoclinic in space group P21/c. The thermal expansion in TcO2 is highly anisotropic with ...Open AccessArticle -
Magnetic and structural studies of Sc containing ruthenate double perovskites A2ScRuO6 (A = Ba, Sr).
Published 2017-01-01Ruthenium containing double perovskites A2ScRuO6 have been synthesized as polycrystalline powders and structurally characterized using a combination of synchrotron X-ray and neutron powder diffraction methods. When A = ...Open AccessArticle -
Spin-orbit coupling controlled ground state in the Ir(V) perovskites A2ScIrO6 (A = Ba or Sr)
Published 2017-01-01The structural and magnetic properties of the two Ir(V) perovskites Ba2ScIrO6 and Sr2ScIrO6 have been established. The structures were refined using a combined neutron and Synchrotron data set. At room temperature the ...Open AccessArticle
