Superconducting Properties of YBa2Cu3O7/PrBa2Cu3O7 Superlattices find that the broadening of the transition is strongly reduced for d-PrBCO larger than 12? and for samples with d-PrBCO>24? no measurable effect of a 9 Tesla magnetic field parallel to the layers could be detected. We believe that this insensitivity to the magnetic field comes from the absence of flux flow in these modulated structures.

In-Situ Growth of Y-Ba-Cu-O Films by High Pressure DC Sputteringund 80 K. Tc(zero) and Jc(77 K, zero field) of as-deposited film can be improved from 81 K and 3.1x10. A/cm. to 89 K and 3.1x10.A/cm., respectively by annealing it at 940°C for 3 min in flowing oxygen.

Cathodic Sputtering as a Tool for the High-Tc Superconducting Materials Processing evaporation [2], chemical vapor deposition [3], and laser beam deposition [4]. Among these processes the cathodic sputtering is now widely used not only for the deposition of the high-Tc thin films but for the microfabrication of the high-Tc thin film electronic devices.

Factors Affecting Formation of ‘in Situ’ and 110 K Phase Sputtered Bi-Based Superconducting Thin Fil devices, such as SQUID’s, and power transmission. There are two high T., Bi-based superconductors: viz. 85 K Bi.Sr.CaCu.O. or more generally Bi.(SrCa).Cu.O., (2212) and 110 K Si.Sr.Ca.Cu.O., (2223) phases. Thus the Bi-based superconductors provide the advantage of superconducting critical temperatu

In-Situ Growth of Superconducting Films of Bi-Sr-Ca-Cu-O Using Magnetron Sputterings than post-annealed films has been the goal of many researchers. This has been achieved in YBa.Cu.O. at a number of laboratories, but Bi and Tl-based HTS have proven more difficult. We report superconducting films of Bi.Sr.CaCu.O. and Bi.Sr.Ca.Cu.O. made by magnetron sputtering from a bismuth enric
