Abstract
- The pressure dependence of Tc of superconducting PrBa2Cu3Ox was studied by electrical resistance measurements under hydrostatic pressure up to 10 GPa. A large positive pressure coefficient of Tc, dTc/dP, with a maximum of 7. 3K/GPa, was observed. The coefficient was found to vary with the oxygen content of the compounds, in a similar manner as the isostructural YBa2Cu3Ox compound behaves. The present research revealed an opposite pressure effect on Tc with those reported for the Pr-substituted Y-Ba-Cu-O compounds with high Pr concentration.
