Title:
SUPERCONDUCTOR FLUX PINNING WITHOUT COLUMNAR DEFECTS
Document Type and Number:
WIPO Patent Application WO/2020/117369
Kind Code:
A3
Abstract:
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.
