摘要： A method for making superconductive ceramics laminates comprises forming a thick film of a composite oxide comprising bismuth, strontium, calcium, copper and oxygen on a flat plane of a substrate, and orienting and crystallizing the thus formed film by heat treatment to cause the c-axis of composite oxide crystals to be substantially perpendicular to said flat plane of said substrate. An intermediate layer formed of a noble metal, MgO, SrTiO.sub.3, yttria-stabilized zirconia or an oxide of a superconductive ceramics-constituting element may be interposed between the film and the substrate.

摘要： A compacted and highly oriented microstructure of the bulk-shaped Bi-Sr-Ca-Cu-O system oxide superconductor is obtained by the intermediate pressing method of the present invention. The growth rate of the high critical temperature phase in the bulk of Pb-doped Bi-Sr-Ca-Cu-O system oxide superconductor is also much improved and the sintering duration for obtaining a single phase having a high critical temperature is shorteneed by this method. Additionally, a higher critcal current density of Bi-Sr-Ca-Cu-O system oxide superconductor is obtained by the working under pressure process after cooling between a first and a second sintering step. Furthermore, the magnetic field dependence of the critical current density of Bi-Sr-Ca-Cu-O system oxide superconductor is also improved by the method of the present invention. The thus intermediate pressing process between the first and second sintering step of the present invention may be applied so easily as to facilitate the manufacture of tapes, wires, discs or the like of the Bi-Sr-Ca-Cu-O system oxide superconductor.

摘要： A substrate electrode having a plurality of substrate holders capable of causing a substrate to tilt by an arbitrary angle .theta. relative to the horizontal plane is provided. A plurality of auxiliary electrodes are arranged substantially vertically below the substrate electrode and between the substrate electrode and a target. The substrate electrode and the auxiliary electrodes are electrically insulated from the target. Bias voltage applied to the substrate electrode and the auxiliary electrodes causes the plasma boundary between the cathode dark space and the negative glow to form a cathodic plasma space having a parabolic section, thus forming a crystal-oriented thin film on the substrate surface.
