Influence of surrounding vortices on critical current of a Nb/Al-AlO x /Nb Josephson junction

Resistively shunted Nb/Al-AlO x /Nb Josephson junctions have been widely used in large-scale superconducting electronics such as the single-flux quantum circuit. The critical current primarily determines the working margin of the circuit. The distribution of vortices in the niobium film around super...
