Synthesis and characterization of the new two-dimensional Heisenberg antiferromagnet double perovskite BaLaCuSbO6
(Royal Society of Chemistry, 2015-03)
The BaLaCuSbO6 double perovskite has been successfully synthesized by solid state reaction under an air atmosphere. Its structure was refined using powder neutron diffraction in the monoclinic space group I2/m with a 4% ...
Electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6
(IOP Publishing, 2014-04)
In this work, we present a detailed study of the structural and the electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6. All calculations were performed with the Full-Potential Linear Augmented Plane Wave method ...
La3+ doping of the Sr2CoWO6 double perovskite: A structural and magnetic study
(Academic Press Inc Elsevier Science, 2008-11)
La-doped Sr2CoWO6 double perovskites have been prepared in air in polycrystalline form by solid-state reaction. These materials have been studied by X-ray powder diffraction (XRPD), neutron powder diffraction (NPD) and ...
The strongly defective double perovskite Sr11Mo4O23: Crystal structure in relation to ionic conductivity
(IUCr Journals, 2014-07)
The crystal structure and ionic conductivity properties of a novel microcrystalline Sr11Mo4O23 ceramic material are presented. This material has been prepared by thermal treatment up to 1473 K, in air, of previously ...
Synthesis, structural characterization and magnetic properties of the monoclinic ordered double perovskites BaLaMSbO6, with M = Mn, Co and Ni
(2014)
Double perovskites BaLaMnSbO6, BaLaCoSbO6 and BaLaNiSbO6, were synthesized by conventional ceramic method in air, as polycrystalline powders. The Mn and Ni compounds belong to the I 2/m monoclinic space group, while the ...
Sr 2 Fe 1+: X Re 1- x O 6 double perovskites: Magnetoresistance and (magneto)thermopower
(Royal Society of Chemistry, 2019-04)
Polycrystalline Sr2Fe1+xRe1-xO6 samples have been synthesized and structurally characterized by X-ray powder diffraction, transmission electron microscopy and X-ray absorption spectroscopy. Resistivity strongly increases ...
Ferrimagnetic order in the insulating Sr3Fe2ReO9 double perovskite

Structural evolution of the double perovskites Sr2B'UO6 (B' = Mn, Fe, Co, Ni, Zn) upon reduction: Magnetic behavior of the uranium cations
(Pergamon-Elsevier Science Ltd, 2011-11)
We describe the preparation of five perovskite oxides obtained upon reduction of Sr2B′UO6 (B′ = Mn, Fe, Co, Ni, Zn) with H2/N2 (5%/95%) at 900 °C during 8 h, and their structural characterization by X-ray powder diffraction ...
