摘要： A superconducting wire includes first and second superconducting layers disposed on one or more substrates in stacked relationship, the first superconducting layer comprising a high temperature superconducting oxide of a first composition and the second superconducting layer comprising a high temperature superconducting layer of a second composition, wherein the first and second compositions are different. The first superconductor layer optionally includes a high temperature superconductor composition selected to provide enhanced critical current (Ic(c)) in the presence of magnetic fields perpendicular to surface of the superconducting layer (H//c). The second superconductor layer optionally includes a high temperature superconductor composition selected to provide enhanced critical current (Ic) in the presence of magnetic fields parallel to surface of the superconducting layer (H//ab).

摘要： A method of making an oxide superconductor article includes converting an oxide superconducting precursor into an oxide superconductor by thermo-mechanical processing using intermediate rolling deformation and heat treatment (including liquid-phase sintering and low temperature baking) and applying an additional heat treatment after the material is fully processed (including optional liquid-phase sintering and low temperature baking) to decompose any secondary phase remaining at the grain boundaries and to promote diffusion of the secondary phase into the oxide grain, where they form 2223 phase. The material has a better superconducting grain connectivity and improved superconducting transport property.

摘要： Under one aspect, a method of making a superconductor wire includes providing an oxide superconductor layer overlaying a substrate; forming a substantially continuous barrier layer over the oxide superconductor layer, the barrier layer including metal; depositing a layer of metal particles over the barrier layer, said depositing including applying a liquid including metal particles over the barrier layer; and sintering the layer of metal particles to form a substantially continuous metal layer over the barrier layer. In one or more embodiments, the oxide superconductor layer is oxygen-deficient, and the method may include oxidizing the oxygen-deficient oxide superconductor layer. At least a portion of the sintering and the oxidizing may occur simultaneously, for example by performing them at an oxygen partial pressure and a temperature sufficient to both sinter the metal particles and to oxidize the oxygen-deficient oxide superconductor layer.
