Summary

The authors present measurements of the uniaxial pressure dependence of critical temperature of untwinned YBCO crystals with various oxygen stoichiometries. For all samples investigated, critical temperature decreases for pressure along a, increases for pressure along b, and, in oxygen deficient samples, increases strongly for pressure along c. The presence of singularities in the electronic density of states close to the Fermi energy is a possible origin of the observed behaviour.
