Highly stable reference voltage using the Josephson effect, which has been used as a primary standard for DC voltage, can realize a highly stable reference voltage source that can be directly used in cryogenic and high magnetic field environments by extending its application range to magnetic field environments. In this presentation, we will report the results of a prototype magnetic shield of a superconductor, which was fabricated based on design information and mounted in a dilution refrigerator, and the measurement of the magnetic field generated by a superconducting magnet using a Hall device installed near the Josephson device.
