Abstract
A low-cost electrodeposition (ED) method is reported for fabrication of high-temperature Tl-oxide-based superconductors. Recent studies on the development of biaxially textured ED films on single-crystal and rollingassisted biaxially textured Ni substrates are presented. Polefigure measurements of electrodeposited (Tl, 8i)-(Sr, Ba)-CaCu-Ag-O (TBSBCCO) films, with thicknesses between 1-5 urn, clearly show strong biaxial texturing. The rocking curve and phi scan of TBSBCCO on 300 A Ag/LaAIO3, show a full width half maximum (FWHM) of only 0. 9° and 1. 2°, respectively, consistent with a very high-quality film. Transport measurements for the ED films show Jc values up to 7. 84 x 105 A/cmz at 77 K in zero magnetic field. The preliminary results of electrodeposited TBSBCCO film on CeOz/YSZ/CeOz on textured Ni showed primarily 1212 phase with a transport critical current density of 1. 36 x 10s A/cm1 at 77 K in zero field.
