## Title

    Joints Fabricated by Slurry Process

## Description

- description: The properties of superconducting joints for REBa2Cu3Oy (REBCO, RE
    = rare earth) superconducting tapes fabricated using a slurry process were investigated.
    Microstructural observation revealed that a joining layer fabricated using a slurry
    was well-connected to the REBCO layer of the joined tape. The resistance and critical
    current of closed-loop samples containing slurry-processed superconducting joint
    were evaluated using current decay measurements. The joint resistance was found
    to be lower than 10−12 and 10−11 Ω at 4 and 77 K, respectively, in the self-field.
    It is inferred that a persistent current can flow through a slurry-processed superconducting
    joint. Conversely, in-field critical current was low and exhibited hysteresis
    due to weak links in the joining layer.
