Abstract
The resistance and Hall coefficient of a Bi2.2Sr1.8CaCu2O8+y single crystal have been measured under pressure. It is shown from our result that the pressure coefficient of dTc/dP changes from positive to negative with increasing pressure and the maximum superconducting transition temperature appears at a pressure of about 1.05 GPa. The Hall-coefficient result shows a monotonic increase of hole concentration with pressure up to 1.19 GPa. The maximum of the superconducting transition temperature induced by pressure in Bi2.2Sr1.8CaCu2O8+y can be interpreted in terms of the hole concentration passing through an optimal value under pressure.
