Abstract
A two-step fabrication process for the creation of a bi-epitaxial junc tion in thin films of YBa2Cu3O7-x is described. The junction has been fabricated on (100) SrTiO3 substrate using a buffer layer of CeO2. Pol arized light optical microscopy indicates a regular basket-weave micro structure and a granular structure on either side of the junction. The junction shows Josephson critical currents at temperatures upto 74K a nd the critical current increases linearly with decreasing temperature .
