example I

[0187] Epitaxial YBCO films were prepared as follows.

[0188] A biaxially textured 95 atomic percent nickel / five atomic percent tungsten alloy substrate was configured by cold rolling and annealing in strip form (75 mm thick and 1 cm wide). A 2 micron thick nickel layer was formed on the surface of the substrate, and a C2X2 sulfur superstructure was formed on the nickel layer.

[0189] Subsequent deposition of an epitaxial oxide buffer layer to form a structured substrate / Y 2 o 3 / YSZ / CeO 2 heap. Deposition of Y by electron beam vaporization 2 o 3 Seed layer (50 nm thick). Deposition of YSZ barrier layer (300 nm thick) and CeO by RF sputtering 2 Cap layer (30 nm thick).

[0190] A solution based on copper propionate, barium trifluoroacetate, and yttrium trifluoroacetate was coated on CeO 2 on the cap. The film is dried at 60°C in humid air and the resulting material is decomposed in a moist, oxygen atmosphere at a temperature up to 400°C, for the subsequent formatio...

Abstract

Superconductor reactors, methods and systems are disclosed.

Description

technical field [0001] The present invention relates to a superconducting material, a method of making it, and a reactor for making this material. Background technique [0002] Multilayer articles can be used in a variety of applications. For example, superconductors, including oxide superconductors, can be formed from multilayer articles. Typically, such superconductors include one or more layers of superconducting material and a layer, often referred to as a substrate, that enhances the mechanical strength of the multilayer article. [0003] In general, in addition to enhancing the strength of the multilayer superconductor, the substrate can exhibit other specific properties as desired. For example, the substrate may have a low Curie temperature as desired, so that the substrate is not ferromagnetic at superconductor application temperatures. Additionally, it may be desirable that chemicals in the substrate cannot diffuse into the layer of superconductor material. Furt...
