    • In a method for manufacturing a device having a film of high temperature superconductor, a copper substrate is used in the electrophoretic deposition as a cathode on which fine powders of superconductor should be deposited, and the fine powders deposited on the substrate are fired in the conditions that they are sintered partially.In other methods for manufacturing such a device, a desired minute pattern of electrically conductive material as a cathode in the electrophoretic deposition is formed on a substrate, and a minute pattern of fine powders is deposited according to the pattern of the cathode. Then, the fine powders are fired to form a superconductor film. Such a desired pattern of the cathode is formed by the patterning of a film of an electrically insulating substrate. Such a desired pattern of the cathode is also formed by the patterning of an electrically insulating material, applied to an electrically conductive substrate.In a further method for manufacturing such a device, a desired minute pattern of electrically conductive material as a cathode in the electrophoretic deposition is formed on a substrate, while another pattern of electrically conductive material as an anode is formed on the same substrate near the former pattern so as to keep a constant distance.

    • A superconducting magnetoresistive element has superconducting portions having a high critical current density and weak-coupling portions having a low critical current density. The superconducting portions and weak-coupling portions are alternately arranged and connected in series. The superconducting magnetoresistive element is fabricated, for example, by forming semiconductor films at a plurality of sites on a substrate in a manner that the semiconductor films are spaced from each other, then forming a superconducting thin film all over the substrate and processing the superconducting thin film into a line pattern which passes over the plurality of semiconductor films, and heat-treating the substrate to diffuse a constituent element of the semiconductor films in the superconducting thin film. Portions of the superconducting thin film overlying the semiconductor films become the weak-coupling portions and the rest portions of the superconducting thin film become the superconducting portions.

    • A method for sensing an applied magnetic field uses a superconductor element with superconductive material as a sensor. The element is cooled to its superconducting state and current is supplied to the element. An applied magnetic field is applied to the superconducting material and an output from the superconductor element is fed to a feed back power source. In the feedback power source a comparison is made between an input voltage from the superconductive element and a reference voltage. Current is applied to a coil for applying a bias magnetic field to the superconductor element based on the comparison. With this method, the input voltage and the reference voltage are made as equal as possible. A superconductive device includes a coil for applying an AC power source and a coil for applying a DC power source. The DC power source can be set at various values and the application of the DC power source, which is a bias voltage, changes the output of the superconductive element by changing the electrical wave form outputted from the superconductive element.
