Abstract

Measurement of the Hall coefficient in the Ba2Y1-xPrxCu3O7- system has revealed that an increase in Pr concentration reduces the Hall carrier number (1eRH) and its strong temperature dependence. The Cu formal valence calculated from the Pr valence, which has been determined to be +3.5, shows a weakly decreasing dependence on Pr concentration. Tc shows a stronger dependence on the Hall carrier number and the Cu-O formal valence than in the oxygen-depleted Ba2YCu3O7- system. The persistence of the chain band explains this observed difference, suggesting that the actual Cu-O valence dependence of the 90-K superconductor is stronger than that of the 40-K superconductor.
