Synthesis and properties of high-pressure phase [ErxCu3](V4)O12
AbstractA new perovskite-like compound Er0.73Cu3V4O12 (space group Im$$
\bar 3
$$, Z = 2, a = 7.266 Å) has been synthesized barothermally (P = 8.0 GPa, t = 1000°C). Its electrical and magnetic properties have been studied. It is found that the temperature dependence of the electrical conductivity (in the range 78–300 K) has of semiconductor type. The behavior of the impedance and admittance has been analyzed at 290 K and frequencies of 200 Hz to 200 kHz under atmospheric pressure and at high (15–42 GPa) pressures.
