Abstract

The effect of hydrostatic pressure up to 12 kbar on electrical resistance in the basal ab-plane of optimally oxygen-doped Y1–xPrxBa2Cu3O7–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 dTc/dP at zero pressure; however, as the pressure rises, dTc/dP decreases to a level characteristic of undoped Y1–xPrxBa2Cu3O7–δ samples with an optimal oxygen content.
