Abstract
High quality twin-free c-axis oriented YBa2Cu3O7-delta films were grow n by pulsed laser deposition on NdGaO3. We find resistive anisotropies between 1 < rho(a)/rho(b) < 1.6. The resistive anisotropy above T-c a ppears to be correlated to the anisotropy in the critical current belo w T-c. The normal state properties of the chains along b seem to have a significant influence on the superconducting properties of YBa2Cu3O7 -delta.
