Abstract
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.
