Abstract
The ohmic contact between an oxide superconductor and a Au electrode was systematically studied under various temperature conditions. A low resistance ohmic contact below 7×10-8 Ωcm2 between the oxide superconductor EuBa2Cu3O y and a Au electrode is obtained by annealing at 300°C in an oxygen atmosphere. Under these conditions, the intrinsic electrical properties of the superconductor are not changed. In contrast, anomalous behavior is observed when using indium as the contact metal.Keywords
