High-pressure nonstoichiometric phase SmxCu3V4O12

Perovskite-like nonstoichiometric oxide SmxCu3V4O12 (space group Im\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\bar 3$\end{document}, Z = 2, a = 7.276−7.314 Å) with cationic vacancies and a homogeneity region was prepared barothermally (p = 6.0−9.0 GPa, T = 700−1100°C) for the first time. Structural and isotropic thermal parameters, as well as bond lengths and bond angles, were determined. The compound has metal-type conductivity and paramagnetic properties.
