Abstract

The effect of hydrostatic pressure up to 12 kbar on electrical resistance in the basal ab-plane of optimally oxygen-doped Y_1–xPr_xBa₂Cu₃O_7–δ single crystals doped with praseodymium (х≈0.23) has been investigated. It was determined that the introduction of praseodymium leads to a fivefold increase in the baric derivative dT_c/dP at zero pressure; however, as the pressure rises, dT_c/dP decreases to a level characteristic of undoped Y_1–xPr_xBa₂Cu₃O_7–δ samples with an optimal oxygen content.
