Abstract

Electrical resistivity measurements of the insulating Ba 1-xKxBiO3 (x = 0, 0.15) under high pressure up to 8 GPa have been performed in order to search for the pressure-induced superconductivity, using a cubic-anvil pressure system. A polycrystal of BaBiO3 has been prepared by the solid-state reaction method. A single crystal of Ba0.85K0.15BiO3 has been synthesized by the electrochemical method from molten salts. The electrical resistivity of both compounds slightly decreases with increasing pressure. However, the temperature dependence still remains semiconductive and no superconductivity is observed.
