    摘要: A magnetic image detection device which measures a magnetic image in the first or second dimension by using a superconducting body. In the magnetic image detection device, multiple band-shaped superconducting bodies are provided in parallel on a nonmagnetic dielectric substrate, and electrodes are provided on both ends of the superconducting bodies so as to form pairs. A detection circuit detects resistance between the electrodes on both ends of the multiple superconducting bodies according to intensity of external magnetic field.

    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.
