Abstract :
The results reported are part of a larger effort, the basic aim of which is to develop high-Tc superconducting composite wires, films, and thin-gauge panels with large current carrying capacity and engineered thermal and mechanical properties. The results relate to the following aspects of this ongoing research effort: the sputtering parameters used to deposit Bi-Sr-Ca-Cu-O films on MgO and other substrates; a dipping technique to produce Bi-Sr-Ca-Cu-O superconducting layers and wires; the postannealing heat treatments; the characterization of the microstructure and crystallographic features of the deposited films; and the superconducting properties of the films, layers, and wires
