Multiferroic double perovskites: Opportunities, issues, and challenges [PDF]
Journal of Applied Physics, 2010 A well-controlled coupled behavior in magnetoelectric materials at room temperature remains challenging. We demonstrate that the self-ordered A2B′B″O6 (e.g., A=La, B′=Mn, and B″=Ni) double perovskites provide a unique alternative opportunity to control and/or to induce such behavior in oxides.

Electronic structure of ordered double perovskite Ba2CoWO6 [PDF]
AIP Conference Proceedings, 2014 Ba2CoWO6 (BCoW) has been synthesized in polycrystalline form by solid state reaction at 1200C. Structural characterization of the compound was done through X-ray diffraction (XRD) followed by Rietveld analysis of the XRD pattern. The crystal structure is cubic, space group Fm-3m (No 225) with the lattice parameter, a=8.210A.
