Electrical properties of YBa2Cu3O7 thin films

Abstract Evaporated and ex situ annealed YBa 2 Cu 3 O 7 epitaxial thin films have been laser patterned to form a ring and a long (5cm) meander track. These samples have been used to study the dependence of the electric field on the applied current in the flux creep regime, using both magnetic and transport measurements.
