## Description

- description: Rare-earth barium copper oxide (REBCO) superconductors can be applied
    to superconducting magnets in low-temperature and high-magnetic-field and electric
    power equipment. Currently available superconducting wires supplied by many companies
    are tape-shaped, and a thin REBCO film is formed by depositing multiple buffer
    layers on a thin metal substrate. Coated conductors fabricated on such a flat
    substrate have a structure close to a single crystal and have high critical current
    density properties. In contrast, reducing the screening current is an important
    issue for practical applications such as high-field superconducting coils. In
    this study, we proposed a patterned multi-filamentary thin film with a stripe
    pattern, fabricated on a substrate via photolithography. YBa2Cu3Ox was deposited
    onto stripe with Nb metal. Any stripe material can be used to separate superconducting
    and non-superconducting wires based on magneto-optical observations. Based on
    TEM/STEM-EDX observations, impurity phases such as NbBaO were formed on the STO/Nb
    strip. These results suggested that the use of a substrate with a stripe pattern
    is useful for fabricating multifilamentary coated conductors.
