High Tc superconducting thin films by rapid thermal annealing of Cu/BaO/Y2O3 layered structures

View publication

Abstract

Superconducting thin films of YBaCuO have been formed using rapid thermal annealing of Cu/BaO/Y2 O3 layered structures, which were deposited on MgO substrates by electron beam evaporation. The best film has an onset temperature of 94 K and zero resistance at 84 K. The dependence of the film characteristics and superconducting transition temperature on the annealing conditions has been studied. Auger depth profiling was used to examine the interdiffusion between the film and the MgO substrate.
