✦ Synopsis

Hall coefficient R H and superconducting transition temperature T: in Y09Cao~Ba2Cu3Oy with 6,59<y_<7.01 have been measured under ambient pressure and under high pressure up to 2GPa. It is found that the relation of Tc and Hall number l/eR H under high pressure is explained in terms of the change in the carrier density and the pressure-induced pairing effect which depends on the oxygencontent.
