If a current exceeds a critical value, superconductivity is lost; the barrier then only passes the "normal" low tunneling current and a voltage develops across the junction.
A particular type of interferometer results when utilizing two junctions that abide by this effect. If a current exceeds a critical value, superconductivity is lost; the barrier then only passes the "normal" low tunneling current and a voltage develops across the junction. If a magnetic field is applied below the critical current value, the current density changes regularly with distance across the junction. FTP, identify this effect of superconductivity that results when two materials are separated by a thin insulating junction and undergo a tunneling through the barrier.
