Abstract A powder mixture of UO 2 and TiO was mechanochemically treated in a planetary ball mill under Ar atmosphere for 1 h using tungsten carbide vial balls as the milling medium. Such mechanochemical (MC) treatment reduced crystallinity . The heated at 700–1,300°C 6 analyzed by X-ray diffraction analysis, scanning electron microscopy-energy-dispersive spectroscopy, absorption fine structure ...

Iron oxide is one of the most important components in Earth's mantle. Recent discovery stable presence Fe5O6 at mantle environment stimulates significant interests understanding this new category iron oxides. In paper, we report electronic structure and magnetic properties calculated by density functional theory plus dynamic mean field (DFT+DMFT) approach. Our calculations indicate that a condu...

The reaction between P2-type honeycomb layered oxides Na2Ni2TeO6 and K2Ni2TeO6 enables the formation of NaKNi2TeO6. compound is characterized by X-ray diffraction 23Na solid-state nuclear magnetic resonance spectroscopy, structure discussed through density functional theory calculations. In addition to Ni/Te cationic ordering, NaKNi2TeO6 exhibits a unique example alternation sodium potassium la...

We study the effects of interfacing van der Waals ferromagnet Cr 2 Ge Te 6 with oxide layers, such as NiO and MgO, in a few different configurations. For this, magnetic hysteresis curves, obtained by magneto optical Kerr effect, flakes similar thicknesses were evaluated. Compared to properties bare , we observed an increased perpendicular anisotropy enhanced Curie temperature /NiO heterostructu...

An overview of recent debate about the origin green emission in Cs 4 PbBr 6 and/or CsPbBr 3 is presented; several possibilities are discussed, including a defect-mediated event or nano-inclusions embedded within .

Cs2AgBiBr6 is a stable halide double perovskite with bandgap of about 2.2 eV. Therefore, it intensively studied as potential lead-free alternative to hybrid solar cell absorber materials such methylammonium lead iodide. However, power conversion efficiencies cells this material have not yet exceeded 3%. A detailed understanding the electronic structure difficult, due variance reported data and ...

The study of the magnetic, electronic transport, and magnetotransport properties La0.9Ce0.1Fe12B6 itinerant-electron system has been performed by combining magnetization, electrical resistivity, magnetoresistance experiments. Along with antiferromagnetic (AFM) ordering at TN = 35 K, two consecutive magnetic transformations, antiferromagnetic–ferromagnetic (AFM–FM) ferromagnetic–paramagnetic (FM...
