    摘要： A Josephson transmission line device comprising a Josephson transmission line consisting of a pair of superconducting layers and a junction layer disposed between the superconducting layers to constitute a Josephson junction; a fluxon stopping position constituted by at least one resistor element in at least a part of the Josephson transmission line; a fluxon driving current source connected to the resistor element; a fluxon generating current source connected to the Josephson transmission line for generating fluxons therein; and an output circuit for extracting the fluxons generated in the Josephson transmission line as output signals. Fluxons generated in the Josephson transmission line can be made to stop at and depart from the stopping positions by selective application of fluxon driving current. Therefore, the Josephson transmission line can, alone or in combination with other such lines, be made to operate as compact, high-speed, low power-dissipation Josephson electronic circuit devices capable of functioning as logic circuits, memories, pulse generators, etc.

    摘要： A magnetic switching device of the present invention includes: at least one transition member; at least one electrode; and at least one free magnetic member. The transition member contains a perovskite compound that contains at least a rare earth element and an alkaline-earth metal, the electrode and the free magnetic member are arranged in parallel and in a noncontact manner on the transition member, at least one of the free magnetic members is coupled magnetically with the transition member, and the transition member undergoes at least ferromagnetism-antiferromagnetism transition by injecting or inducing electrons or holes, whereby a magnetization direction of at least one of the free magnetic members changes. This configuration is applicable to a magnetic memory that records/reads out magnetization information of the free magnetic layer and various magnetic devices that utilize a resistance change of the magnetoresistive effect portion.
