ABSTRACT:
A switching and storage device is described in which a superconductor is arranged in regard to a magnetic or magnetizable element so that the magnetic field of the element surrounds the superconductor. The inner inductivity of the superconductor is subject to strong variation if at least one lateral dimension of the superconductor is comparable with or smaller than the penetration depth of the field into the superconducting material. If the superconductor is bifurcated, an electric current of sufficient magnitude fed externally distributes to flow essentially in one branch while the other branch essentially remains currentless. External control by a magnetic field can switch the current into the other branch, i.e., the device is bistable. The switching process inherently is fast and of low power consumption.
