Josephson sensor device with superconducting parts comprising metal oxide superconductor material

摘要

The Josephson sensor device (7) for detecting a weak magnetic field contains superconducting conductor parts (4) comprising a high-Tc superconducting material and a plurality of Josephson junctions (contacts) (3j). According to the invention, the superconducting conductor parts (4) are intended to form a conductive track, in which the plurality of Josephson junctions (3j) are arranged one after the other as field-sensitive elements to form a series circuit (R) in the conduction direction. The Josephson junctions (3j) are preferably grain-boundary junctions. <IMAGE>
