Abstract

Thick films of the high-temperature superconductor Tl₁Ba ₂Ca₂Cu₃O_y with high current density J_c have been deposited on polycrystalline Ag substrates by a spin-coating method. The spin-coated precursor films were annealed in a two-zone Tl reaction furnace. Film thicknesses ranged from 10 to 30 μm, leading to good total current capabilities. The films have highly-textured c-orientation as evidenced by rocking curves with FWHM of 4°for the (006) peak. Scanning electron micrographs revealed a dense, plate-like layered structure and almost no reaction between the film and the Ag substrate. Values of J_c (77 K) up to 2.5×10⁴ A/cm² in zero field and more than 1000 A/cm² in a 1 tesla field (H∥c axis).
