Abstract

We probe the effect on T_c of in-plane uniaxial stress applied to the high-temperature superconductor YBa₂Cu₃O_6.67. We find a highly anisotropic response. Under compression along the b axis, which reduces the orthorhombicity of the CuO₂ planes, T_c is broadly flat for stresses up to at least 1.7 GPa. Under compression along the a axis, T_c decreases steeply. For stresses beyond ≈1 GPa the decrease is quasilinear. We hypothesize that superconductivity is suppressed by competition with uniaxial charge density wave order, which has been found to onset at ≈1 GPa.
