Abstract
Non-vacuum electrodeposition and spray deposition 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 cm−2 at 4 K in zero field. The samples were characterized by x-ray diffraction including θ/2θ, pole figures, omega scans, phi scans, resistance versus temperature (R–T), magnetization measurements, transmission electron microscopy and scanning electron micrographs.
