Abstract :
An electrodeposition process was used to deposit Bi-2212 precursor films. Biaxially textured Bi-2212 superconductor films were prepared from electrodeposited precursor films by melt-quench/melt-growth processing on Ag-coated LAO substrates. Magnetization measurements for the electrodeposited, Bi-2212 superconductor films show critical current density values greater than 5 × 106 A/cm2 at 4 K in zero field.
