Microstructural Investigation of YBa2Cu3O7-δ Films Deposited by Laser Ablation from BaF2/Y2O3/CuO Tafilm composition, in particular, is strongly dependent on the uniformity and energy density of the laser beam. Heating the substrate to high temperatures (over 650°C) during the deposition has resulted in much improved values for both T. and J., but the inherent sensitivity to the deposition paramet

A Simple Technique to Prepare High Quality Superconducting Bi-Sr-Ca-Cu-Oxide Thin Films to its ease of thin film preparation and chemical stability. The discovery of the Bi-Sr-Ca-Cu-Oxide system with several superconduct ing phases . generated much fundamental as well as practical interest. It was readily seen that at least two superconducting phases of this compound exist with critic

Superconducting Properties of Magnetron Sputtered Bi-Sr-Ca-Cu-O and Tl-Ba-Ca-Cu-O Thin Filmshe film. The Tl-based films form at least three compounds (2212, 1223, 2223) with T.’s ranging from ≈ 100 K to 114 K and grow best on (100) and polycrystalline Y-ZrO. substrates. Annealing conditions are particularily difficult because of the volatility of thallium and require samples to be annealed
