Electrodeposition of yttrium, barium and copper in metallic state from DMSO (dimethylsulfoxide) solutions containing cyanide as complexing agent for copper leads to the preparation of YBa 2 Cu 3 O 7 - δ directly over metallic substrates. Superconducting properties on coatings obtained by this procedure showed the largest T c and J c obtained to date by techniques involving electrodeposition of precursors over metallic silver substrates. However, those properties can be further improved by slight modifications of the thermal treatments and by mechanically pressing of the deposit before the oxidation process. Values of J c near 3000 A/cm 2 have been obtained at liquid nitrogen temperatures in the absence of applied magnetic field. Notably, the initial pressing of the precursors coating leads to preferentially oriented crystals after the oxidizing process.
