摘要： A SQUID for detecting a weak magnetic field is constructed of a sensor coil which detects a signal magnetic flux, and a superconducting loop which is magnetically coupled with the sensor coil to generate a periodic voltage corresponding to an interlinking magnetic flux from the sensor coil. The periodic voltage from the SQUID is amplified, and is taken out. The periodic voltage taken out is synchronously detected by a phase-sensitive detecting amplifier. The synchronously-detected signal is converted into a light signal, which is fed back to the SQUID. The light signal fed back is converted into an electric signal by a superconducting phototransistor which is arranged in a cryogenic atmosphere. A magnetic flux corresponding to the electric signal from the superconducting phototransistor is fed back to the superconducting loop by a feedback coil.

摘要： A process for controlling an oxygen content of a non-superconductive or superconductive oxide is provided, in which a beam of particles such as ions, electrons or neutrons or an electromagnetic radiation is applied to the non-superconductive or superconductive oxide of a perovskite type such as YBa.sub.2 Cu.sub.3 O.sub.7-x, thereby increasing or reducing the oxygen content of the oxide at the sites of oxygen in the crystal lattice of the oxide. Furthermore, a superconductive device such as a superconductive magnet, superconductive power transmission wire, superconductive transformer, superconductive shield, permanent current switch and electronic element is made by utilizing the process for controlling the oxygen concentration of the superconductive oxide.

摘要： A superconducting field effect transistor which is very small in size and high in dimensional accuracy, has a first layer of material forming a control electrode and a second layer of another material is disposed on said first layer. A width of said first layer in a direction toward a superconducting source electrode and a superconducting drain electrode is narrower than a width of the second layer in the same direction. Polycrystalline silicon may be used as the control electrode while the second layer can be made of silicon nitride. Furthermore, a side surface of the control electrode may be coated with an insulator film. Accordingly, the above transistor has a fine structure gate electrode part that can be fabricated easily and accurately.
