## Description

- description: We investigate the magnetic-field hysteresis effect on critical current
    (Ic) of Sn-Pb solders by focusing on flux trapping states. A clear difference
    in Ic is observed between the zero-field-cooled (ZFC) and field-cooled (FC) states.
    The Ic for the FC sample is 127.7 A which is larger than Ic = 107.8 A for the
    ZFC sample at H = 300 Oe. Through investigation of Ic and magnetization, we propose
    that the phase-separated superconducting alloys can show clearly enhanced Ic by
    flux trapping, and the exotic states are potentially available for designing superconducting
    applications.
