This paper reports on thin film superconductors of YBaCuO, fabricated via an electrodeposition process from a single electrolyte solution consisting of the nitrate salts of Y(III), Ba(II), and Cu(II) dissolved in an organic solvent dimethyl sulfoxide. Nominal deposition potentials ranging from {minus}2.5 to {minus}4 V (vs. Ag/AgNO{sub 3} reference electrode) are employed. The postannealed electrodeposited films show reproducible zero resistance at about 74 K on Ni, 78 K on MgO, and 91 K on cubic zirconia substrate. The Meissner measurements also support the superconductivity behavior of the thin films. Critical current density of the films deposited on ZrO{sub 2} is 4000 A/cm{sup 2} in zero field at 4 K, and 360 A/cm{sup 2} at 77 K, zero field.
