摘要： A logic circuit device includes a superconductive body formed of a ceramic superconductive material. The ceramic superconductive material has random grain boundaries which act as weak couplings. The ceramic superconductive material also has a magneto-resistive property. There is at least one conductor arranged near the ceramic superconductive body in order to exert a magnetic field on the ceramic superconductive body. The ceramic superconductive body changes its resistance in response to the magnetic field generated by the conductor. The ceramic superconductive body can be used as part of a logic circuit.

摘要： A superconductive magneto-resistive device includes superconductive ceramic films having a magneto-resistive effect. In the superconductive magneto-resistive device, the superconductive ceramic films are laminated one by one, and the adjacent superconductive ceramic films are insulated by each electrical insulation film, respectively, except for one portion of each of the adjacent superconductive ceramic films, resulting in that the superconductive ceramic films are connected in series. Furthermore, a pair of electrodes is arranged on the upper-most and lower-most superconductive ceramic films.
