LaSrMnCoO6: a new cubic double perovskite oxideLaSrMnCoO6: a new cubic double perovskite oxide Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-12-032003enSingle-phase polycrystalline powder samples of the double perovskite oxide LaSrMnCoO6 were synthesized by the Pechini (citrate-gel) technique. The structural, magnetic and electrical properties of the obtained powders were investigated by X-ray diffraction, electron microscopy, dc magnetization, ac susceptibility and dc resistivity measurements. The crystal structure of the new compound was found to be cubic of space group Full-size image (<1 K) at room temperature. Below 225 K, the samples exhibit ferrimagnetic behavior with a spin-glass-like character. Resistivity measurements indicate semiconducting behavior with two different conductivity mechanisms: thermally activated behavior below 190 K and variable range hopping above 190 K.http://creativecommons.org/licenses/by/4.0/Journal of Solid State Chemistry1732350-354 Androulakis, John G Katsarakis, Nicolas J.
