N2 - The superconducting transition temperature (Tc) of Ba0.62K0.38Bio3 (Tc=30 K) has been measured under high pressure up to 8 GPa. It is observed that Tc increases initially with pressure, as reported by Uwe et al., Shirber et al. and Huang et al., but decreases above 4 GPa. The Hall coefficient of Ba0.62K0.38BiO3 has been measured up to 1.2 GPa. The absolute value of the Hall coefficient decreases with pressure by 10% GPa, the value of which is almost the same as that obtained in most CuO-based high-temperature superconductors.
