NOVELTY - Invention relates to cryoelectronic devices and can be used in measurement, radiotechnical and information systems, working at low temperatures. The superconducting device with a Josephson junction has a weak coupling area in form of a thin-film layered structure ferromagnetic material-normal metal-ferromagnetic material, formed on a substrate, electrodes of the superconductor, connected to oppositely lying faces of the said layered structure. The layer of ferromagnetic material is made with possibility of turning magnetisation vectors about each other in the plane of the layered structure from antiferromagnetic to ferromagnetic stage with provision for generation of a triplet type of superconducting coupling in the weak coupling area. USE - Physics. ADVANTAGE - Invention is aimed at providing for efficient control of critical current of Josephson junctions using an external magnetic field by forming a range of independent channels for its flow, also as a result of providing for conditions for generating triple type of superconducting coupling weakly damped in the weak coupling area.
