摘要：

A low-cost electrodeposition (ED) method is reported for fabrication of high-temperature TI-oxide-based superconductors. Recent studies on the development of biaxially textured ED films on single-crystal and rolling-assisted biaxially textured Ni substrates are presented. Pole-figure measurements of electrodeposited (TI, Bi)-(Sr, Ba)-Ca-Cu-Ag-O (TBSBCCO) films, with thicknesses between 1-5 mu m, clearly show strong biaxial texturing. The rocking curve and phi scan of TBSBCCO on 300 Angstrom Ag/LaAlO3, show a full width half maximum (FWHM) of only 0.9 degrees and 1.2 degrees, respectively, consistent with a very high-quality film. Transport measurements for the ED films show J(c) values up to 7.84 x 10(5) A/cm(2) at 77 K in zero magnetic field. The preliminary results of electrodeposited TBSBCCO film on CeO2/YSZ/CeO2 on textured Ni showed primarily 1212 phase with a transport critical current density of 1.36 x 105 A/cm(2) at 77 K in zero field.
