Abstract

We have developed a novel superconducting switch where the states of a quasiparticle tunnel junction (detector) are set with an external magnetic field generated by a control superconducting strip. Because the strip is only slightly overlaps the underlying junction, its non-uniform field with a high concentration near the edge strongly influences the junction current-voltage characteristics. A prototype of the device proposed has been realized on the base of thin Pb films separated by Sn oxide layers. A semiquantitative model of the switch operation using the critical-state approach is in good agreement with experimental data. After miniaturizing, applications in high-frequency superconducting microelectronics seem to be practically promising
