Abstract:

New ACu(3)V(4)O(12) (A=Gd, Tb, Er) phases have been prepared at high pressure and high-temperature conditions (P approximate to 8-9GPa, T approximate to 1000 degrees C) in a toroid-type high pressure cell. These compounds crystallize in the cubic symmetry with a perovskite-like structure. At ambient pressure, they are paramagnetic and have activation-type conductivity. The effect of high pressure (10-50GPa) on the electrical properties of the materials was analyzed in the temperature range from 78 to 300K. Pressure ranges of the transition from activation type to metallic conductivity have been determined. The crystal structure of ACu(3)V(4)O(12) (A=Gd, Tb, Er) was found to be stable up to 50GPa.
