Biaxially textured superconductor Bi-oxide films via an electrodeposition process

摘要

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 /spl times/ 10/sup 6/ A/cm/sup 2/ at 4 K in zero field.
