The double perovskite La2NiMnO6 (LNMO) exhibits complex magnetism due to the competition of magnetic interactions that are strongly affected by structural and inhomogeneities. In this work, we study effect oxygen annealing on structure epitaxial thin films grown pulsed laser deposition. key observations a longer time leads reduction saturation magnetization an enhancement in ferromagnetic trans...

Abstract Thermoelectric properties of single crystal Ta 2 PdSe 6 is investigated by means transport measurements, and a density functional calculation. We found giant Peltier conductivity 100 A cm −1 K at 10 successfully explained it conventional semiconductor theory. concluded that an uncompensated semimetal, high mobility, heavy effective mass are responsible for the conductivity. Our finding...

Iodide elpasolites (or double perovskites, A2B′B″I6, B′ = M+, B″ M3+) are predicted to be promising alternatives lead-based perovskite semiconductors for photovoltaic and optoelectronic applications, but no iodide elpasolite has ever been definitively prepared or structurally characterized. widely unstable due favorable decomposition the competing A3B2I9 (B phase. Here, we report results of syn...

Abstract Bystrite is redefined as a four-layer cancrinite-group mineral with the Losod-type framework and end-member formula Na 7 Ca(Al 6 Si O 24 )S 5 2– Cl – . The known only at Malo–Bystrinskoe gem lazurite deposit, Baikal Lake area, Siberia, Russia. associated minerals are calcite, lazurite, sodalite, fluorapatite, phlogopite, diopside, dolomite plagioclase. brittle, Mohs hardness of distinc...
