Structure and Magnetism in Sr1-xAxTcO3 Perovskites. The importance of the A-site cation.
Published 2017-01-01The Sr1-xBaxTcO3 (x = 0, 0.1, 0.2) oxides were prepared and their solid-state and magnetic structure studied as a function of the temperature by x-ray and neutron powder diffraction. The refined Tc moments at room temperature ...Open AccessArticle -
The ferroelectric phase of CdTiO3. A powder neutron diffraction study.
Published 2011-01-01The synthesis of bulk samples of polycrystalline CdTiO3 in both the rhombohedral ilmenite and orthorhombic perovskite forms is described and the structures of these have been refined using powder neutron diffraction data. ...Open AccessArticle -
Low temperature structure and the ferroelectric phase transitions in the CdTiO3 perovskite
Published 2017-01-01The paraelectric-ferroelectric transition in CdTiO3 has been monitored using high resolution neutron diffraction data. This necessitated preparing a sample enriched in 114Cd. A subtle, but significant, anisotropy in the ...Open AccessArticle -
Thermal Expansion in BaRuO3 Perovskites – an unusual case of bond strengthening at high temperatures
Published 2017-01-01The temperature dependence of the structures of three polytypes of BaRuO3 have been investigated between room temperature and 1000 °C using high resolution Synchrotron X-ray diffraction. The structural studies reveal a ...Open AccessArticle -
Structure and phase transition in BaThO3: A combined neutron and synchrotron X-ray diffraction study
Published 2017-01-01The structure of BaThO3, obtained by solid state synthesis, was refined for the first time by the Rietveld method using a combination of synchrotron X-ray and neutron powder diffraction data. BaThO3 has an orthorhombic ...Open AccessArticle
