Abstract
A coplanar-type NbN-La1-x Ca x MnO z (x=0.23)-NbN junction was fabricated on MgO(100) single-crystal substrates by means of electron-beam lithography and the argon ion-beam milling method, and the junction characteristics were measured. The spacing between the NbN electrodes is 0.25 µm and the junction width is 100 µm. Nonlinearity in the current-voltage characteristics is observed below 6 K, and supercurrent through the junction is observed below 3 K. These results indicate the possibility of a novel proximity effect in the junctions of the combination of NbN and La1-x Ca x MnO z as well as for that of Y1Ba2Cu3O y and La1-x Ca x MnO z .Keywords
