Abstract

A low cost electrodeposition method is tested for the fabricating high-temperature superconducting wire or tape. Recent studies on the development of biaxially textured electrodeposited (ED) films on Ag-coated, single-crystal substrates are reported. Pole-figure measurements of electrodeposited (Tl)-Ba-Ca-Cu-O and (Tl, Bi)-(Sr, Ba)-Ca-Cu-Ag-O films on 300 Å Ag/LaAlO₃, with thickness between 1 and 5 μm, clearly show strong biaxial texturing. The omega scan and phi scan of (TlBi)_0.9Sr_1.6Ba_0.4Ca₂Cu ₃Ag_0.2O_x indicate the full width half maximum (FWHM) of only 0.9° and 1.2°, respectively, which indicate a very high-quality film prepared by electrodeposition process. Transport measurements for the ED films show values of 3 × 10⁵ A/cm² at 77 K in zero field. Single-layer thallium-oxide films, with Pb, Bi, and Sr substitution, offer the potential for operation at 77 K in practical magnetic fields of 3-5 T.
