Abstract
Hall coefficient R(H) and superconducting transition temperature T-c i n Y0.9Ca0.1Ba2Cu3Oy with 6.59 less than or equal to y less than or equ al to 7.01 have been measured under ambient pressure and under high pr essure up to 2GPa. It is found that the relation of T-c and Hall numbe r 1/eR(H) under high pressure is explained in terms of the change in t he carrier density and the pressure-induced pairing effect which depen ds on the oxygen-content.
