Description

The influence of high hydrostatic pressure up to 17 kbar on conductivity in the basal ab-plane of slightly Pr-doped (x ∼ 0.05) Y0.95Pr0.05Ba2Cu3O7-δ single-crystal samples with the system of unidirectional twin boundaries is investigated. It is found that, in contrast to undoped YBa2Cu3O7-δ samples with an optimal oxygen content, the application of high pressure leads to a double increase of the values of pressure derivative dTc/dP. Possible mechanisms of high pressure effects on Tc are discussed with taking into account the presence of singularities in the electron spectrum of the charge carriers
