Abstract

High quality twin-free c-axis oriented YBa₂Cu₃O_7-δ films were grown by pulsed laser deposition on NdGaO₃. We find resistive anisotropies between 1 < ρ_a/ ρ_b < 1.6. The resistive anisotropy above T_c appears to be correlated to the anisotropy in the critical current below T_c. The normal state properties of the chains along b seem to have a significant influence on the superconducting properties of YBa₂Cu₃O_7-δ.
