Abstract
A superconducting magnetoresistive element has superconducting portions having a high critical current density and weak-coupling portions having a low critical current density. The superconducting portions and weak-coupling portions are alternately arranged and connected in series. The superconducting magnetoresistive element is fabricated, for example, by forming semiconductor films at a plurality of sites on a substrate in a manner that the semiconductor films are spaced from each other, then forming a superconducting thin film all over the substrate and processing the superconducting thin film into a line pattern which passes over the plurality of semiconductor films, and heat-treating the substrate to diffuse a constituent element of the semiconductor films in the superconducting thin film. Portions of the superconducting thin film overlying the semiconductor films become the weak-coupling portions and the rest portions of the superconducting thin film become the superconducting portions.
