Nonstoichiometric high-pressure phase of Tm^sub x^Cu^sub 3^V^sub 4^O^sub 12

TmxCu3V4O12, a perovskite-like oxide (space group, Im-3; Z = 2; a = 7.279-7.293 Å) containing vacancies in its cationic sublattice, was obtained barothermally (P = 7.0-9.0 GPa, t = 1000-1100°C) for the first time. The temperature dependences on the electrical resistivity (10-300 K) and the magnetic...

Description
Summary:TmxCu3V4O12, a perovskite-like oxide (space group, Im-3; Z = 2; a = 7.279-7.293 Å) containing vacancies in its cationic sublattice, was obtained barothermally (P = 7.0-9.0 GPa, t = 1000-1100°C) for the first time. The temperature dependences on the electrical resistivity (10-300 K) and the magnetic susceptibility (0-300 K) were investigated. It was shown that the oxide TmxCu3V4O12 is characterized by metal-type conductivity and paramagnetic properties.
