The aim of our work is to investigate the Josephson effect in YBa2Cu3O7-δ/PrBa2Cu3O7-δ superlattices. In the case of current flow along c axis direction the superlattice forms an array of artificial Josephson junctions where the YBa2Cu3O7-δ layers are the superconducting electrodes which are separated but Josephson coupled by the YBa2Cu3O7-δ sheets. In this paper we report on the preparation, characterisation and patterning of the superlattices into suitable structures via standard photolithograpy and lift-off technique.
