Structure and magnetic properties of nickel oxide (NiO) nanopowders have been studied by X-ray/neutron diffraction, SQUID magnetometer, micro-Raman spectroscopy. Our diffraction data indicate that at room temperature all NiO powders are antiferromagnetically ordered a rhombohedral (R-3m) phase. The magnetometry Raman spectroscopy measurements support the presence antiferromagnetic ordering.
The crystal and magnetic structure of manganite La0.7Sr0.3MnO3 has been studied in the pressure range 0–7.5 GPa temperature 4–300 K. ferromagnetic state remains stable whole range. Curie increases as d TC/d P = 4.3 K GPa−1. Unlike manganites with orthorhombic structure, pressure-induced increase TC having rhombohedral symmetry may be explained by modification structural parameters only. difference between properties structures under high is discussed terms MnO6 octahedra.
Experimental investigation of the phase diagram system carbon dioxide−water at pressures up to 2.7 GPa has been carried out in order explain earlier controversial results on decomposition curves hydrates formed this system. According X-ray diffraction data, solid and/or liquid phases water and CO2 coexist room temperature within pressure range from 0.8 2.6 GPa; no clathrate are observed. The neutron experiments involving samples with different CO2/H2O molar ratios, data show that hydrate...
The crystal structure, Raman spectra, and magnetic structure of ${\mathrm{La}}_{0.5}{\mathrm{Ca}}_{0.5}\mathrm{Mn}{\mathrm{O}}_{3}$ were studied at high pressures up to 31 $6.2\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$. A structural transition from orthorhombic monoclinic phase was found $P\ensuremath{\sim}15\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$ room temperature. charge-exchange-type antiferromagnetic ground state is stable under pressure with...
The results of the measurements electrical and Hall resistivities on polycrystalline PbS films doped with iodine obtained through hydrochemical deposition are presented.
The Li1.5Al0.5Ge1.5(PO4)3 (LAGP) and Li1.6Al0.5Ge1.5P2.9Si0.1O12 (LAGPS) compounds with the NASICON structure have been studied both theoretically experimentally. theoretical approach involved analyzing free space in crystal structures (geometrical-topological analysis, GT), calculating ion migration energies using bond valence site energy (BVSE) method, determining ionic conductivity at various temperatures through kinetic Monte Carlo simulations. Density functional theory (DFT)...
Water cages: A water framework consisting of uniform space-filling polyhedral cages containing tetrahydrofuran molecules has been detected in a new clathrate hydrate formed under pressure 0.8 GPa. Topologically the cage represents tetradecahedron with four tetra-, penta-, and six hexagonal faces (see picture).
The structure peculiarities of K0.9Fe0.9Ti0.1O2 that favor the emergence a superionic state have been studied using neutron powder diffraction data as function temperature. migration paths in both undoped and doped potassium ferrite were modeled by topological (tiling) DFT methods. It is shown heating low-temperature phase leads to increase ionic conductivity thanks widening channels appearance thermally induced cation vacancies. calculated barrier found not exceed 0.3 eV/ion all phases,...
