| Abstract: | A new perovskite-like compound Gd x Cu3V4O12 (x = 0.67?0.73) is synthesized under high pressures (P = 4?9 GPa) and at high temperatures (T = 1000°C). Its structure (space group Im3, Z = 2, a = 7.2930(5) ?) is estrablished by X-ray analysis. The bond lengths and bond angles are determined. The temperature dependences of electrical resistivity (10?C300 K) and magnetic susceptibility are studied. The high-pressure Gd x Cu3V4O12 phase is found to have a semi-conductor type of conductivity and paramagnetic properties. |
