Description
Thin films of YBa2Cu3O7-δ have been deposited on samples of LaGaO3 substrates by multilayer E-beam evaporation. Alternating layers of Cu, Y2O3, and BaF2 were deposited on polished (001) substrates. An annealing study was performed to thoroughly blend the layers and minimize substrate interdiffusion. Films were prepared by annealing in wet oxygen at temperatures between 800 degrees C and 1000 degrees C. Four point resistance versus temperature curves were obtained to determine the superconducting transition temperature and transition width. Auger depth profiling was performed as a function of annealing cycle to determine the amount of blending of the layers and quantify any substrate diffusion
