説明:

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.
