摘要：

We report on developing a two-layer process to deposit biaxially textured Tl-oxide films by electrodeposition (ED) on Ag-coated, single-crystal substrates. Pole-figure measurements of two-layer, electrodeposited (Tl,Bi)-(Sr,Ba)-Ca-Cu-O (TBSBCCO) films on 300 Angstrom Ag/LaAlO3 (LAO), with thickness between 1 and 5 mu m, clearly show strong biaxial texturing. The omega scan and phi scan of 1.6 mu m (TlBi)(0.9)Sr1.6Ba0.4Ca2Cu3Ag0.2Ox films indicate the full width at half maximum (FWHM) of only 0.92 degrees and 0.6 degrees, respectively, indicating a very high-quality film prepared by the ED process. Transport measurements for the electrodeposited, thallium-oxide-based superconductor films show values above 10(6) A/cm(2) at 77 K in zero field. (C) 2000 Elsevier Science B.V. All rights reserved.
