Abstract

We have measured the conductance of Y_1-xPr_xBa₂Cu₃O₇/Pb planar tunnel junctions fabricated on thin films where x equals 0, 0.2 and 0.4. When tunneling into the ab-plane, there is a weak decrease in conductance at eV approximately 2k_BT_c, where a superconducting gap is expected. With increasing Pr concentration, the energy where this gap-like feature appears is reduced by an amount commensurate with the reduction in T_c. The gap-like structure in the c-axis tunneling conductance becomes weaker, but displays no change in energy when YBCO is doped with Pr.
