cryoelectronics. SUBSTANCE: proposed superconductor switching member has insulating substrate, superconducting gate film, insulating layer, and superconducting control film. Superconducting films are made of type-II superconductor; condition satisfied for medium-size edge discontinuities deltaω of gate film is deltaω≪ lambdaeff, where lambdaeff is effective penetration depth of magnetic field and for forces fsw ≫ fv, where fsw is force per unit of length of magnetic swirl due to existence of edge magnetic barrier; fv is force per unit of length of magnetic swirl due to internal flaw of film. Bean-Livingston magnetic barrier is realized in superconductor and resulting motion of magnetic swirls initiates controllable voltage across film. EFFECT: enhanced efficiency of switching member control. 3 dwg |
