✦ Synopsis

Static magnetization data for a superconducting thin film based on the TI-Ba-Ca-Cu-O system are presented and discussed. The film, deposited by electron-beam evaporation onto a single crystal SrTiO s substrate, consists of large grains of two superconducting structural phases with their crystallographic c axes normal to the substrate. It exhibits substantial transport critical current density, large diamagnetic shielding, and activated flux creep, consistent with strong intergranular links but weak flux pinning.

We report direct observation of the flux pinning behavior of a TltCa2Ba2Cu30, highly oriented thin film, a randomly oriented polycrystalline thin film and a Tl~CaBa,eu20, single crystal. From the temperature dependence of the critical current densities Jc at zero field, activation energies Uo are es

Thin films of TI-Ca-Ba-Cu oxide were sputter-deposited from dual oxide targets using a symmetrical RF diode sputtering system. Spatially resolved optical emission spectra obtained using a scanning optical fiber for CuO, BaO-doped CuO, and T1-Ca-Ba-Cu-O targets suggest no significant bombardments of
