Abstract

The effect of high hydrostatic pressures of up to 17 kbar on the basal ab-plane conductivity of lightly praseodymium-doped (x ≈ 0.05) Y 1-x Pr x Ba 2 Cu 3 O 7-δ single crystals with unidirectional twin boundaries (TBs) is investigated. It is observed that the application of a high pressure leads to a doubling of the pressure derivative value dTc/dP for Pr -doped samples compared to non-doped YBa 2 Cu 3 O 7-δ samples with optimal oxygen content. Possible mechanisms of the high pressure effect on the critical temperature Tc and the phase segregation in the sample volume are discussed.
