摘要： A superconductive magneto-resistive device includes superconductive ceramic films having a magneto-resistive effect. In the superconductive magneto-resistive device, the superconductive ceramic films are laminated one by one, and the adjacent superconductive ceramic films are insulated by each electrical insulation film, respectively, except for one portion of each of the adjacent superconductive ceramic films, resulting in that the superconductive ceramic films are connected in series. Furthermore, a pair of electrodes is arranged on the upper-most and lower-most superconductive ceramic films.

摘要： A ceramic superconductive magneto-resistive element which has weak grain boundaries is highly sensitive to weak magnetic fields. The magnetic field is measured by the use of an electronic circuit. A comparator is used for comparing an output and reference voltage of the element. When there is a difference between the output and reference voltage bias current is used to equalize these voltages.

摘要： 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.
