Paper Abstract

Thin films of quaternary metal oxides, that are superconducting at temperatures above 77°K, were prepared by electrodeposition of the cations from aqueous electrolytes. The resulting deposits were thermally annealed . We will report the procedure for the electrodeposition of YBa2Cu3O7_delta (The "1-2-3" compound). X-ray diffraction demonstrates clearly the predominant presence of the 1-2-3 phase with minor contamination from other oxides. Conductivity measurements show a transition to the superconducting state around 98°K. Magnetic susceptibility measurements show a transition to a diamagnetic phase around 50°K. Scanning Electron Microscopy shows that the films are porous.
