Superconductor devices
Devices in which the resistance of a single crystal of superconductive material can be varied as a function of the direction of application of a magnetic field relative to the crystal axes are described. A single crystal of a Type 2 superconductor material having a noncubic crystal lattice structure is used. The device has an input and an output conductor and is arranged to be subjected to a temperature below the critical temperature of the superconductor material and to be subjected to a magnetic field greater than its lower critical magnetic field. The orientation of the field relative to the crystal is arranged to be varied so as to vary the resistance of the crystal between the input and output conductor from a first value of resistance to a second value of resistance.
