摘要： A vapor deposition reactor apparatus, systems and methods for deposition of thin films, particularly high-temperature superconducting (HTS) coated conductors, utilize multi-sided susceptors and susceptor pairs for increased production throughput. The reactors may also be configured in multi-stack arrangements of the susceptors within a single reactor chamber for additional throughput gains.

摘要： There is a superconducting article that includes a superconducting film comprising a substrate, one or more buffer layers, and a high temperature superconducting (HTS) layer. The superconducting layer may be comprised of the chemical composition REBa2Cu3O7−x, where RE is one or more rare earth elements, for example: Y, La, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu. The superconductor layer is produced using Photo-Assisted Metal Organic Chemical Vapor Deposition (PAMOCVD) and contains non-superconducting nanoparticles. The nanoparticles are substantially provided in the a-b plane and naturally oriented. The non-superconducting nanoparticles provide flux pinning centers that improve the critical current properties of the superconducting film.

摘要： An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.

摘要： A raw material solution contains a rare earth element carboxylate having 1 or more and 4 or less carbon atoms, a barium carboxylate having 1 or more and 4 or less carbon atoms, and a copper carboxylate having 1 or more and 4 or less carbon atoms, as solutes, and water, two or more types of alcohols having 1 or more and 4 or less carbon atoms, a carboxylic acid having 1 or more and 4 or less carbon atoms, and a basic organic solvent, as solvents. A method for manufacturing an oxide superconducting material comprises a step of preparing a raw material solution, a step of forming a coating film from the raw material solution, a step of heating the coating film to form a calcined film, and a step of heating the calcined film to form an oxide superconducting material.

摘要： A superconductor tape and method for manufacturing, measuring, monitoring, and controlling same are disclosed. Embodiments are directed to a superconductor tape which includes a superconductor film overlying a buffer layer which overlies a substrate. In one embodiment, the superconductor film is defined as having a c-axis lattice constant higher than 11.74 Angstroms. In another embodiment, the superconductor film comprises BaMO3, where M=Zr, Sn, Ta, Nb, Hf, or Ce, and which has a (101) peak of BaMO3 elongated along an axis that is between 60° to 90° from an axis of the (001) peaks of the superconductor film. These and other embodiments achieve well-aligned nanocolumnar defects and thus a high lift factor, which can result in superior critical current performance of the tape in, for example, high magnetic fields.

摘要： A joined body includes: a first superconducting layer, a barrier layer arranged on the first superconducting layer, and a second superconducting layer arranged on the barrier layer. The first superconducting layer, the barrier layer, and the second superconducting layer are formed of a REBCO. A leak current from one of the first superconducting layer and the second superconducting layer to the other of the first superconducting layer and the second superconducting layer is blocked by the barrier layer.
