摘要：

All-oxide superconductor-normal conductor-superconductor (S-N-S) junctions with a planar-type structure are fabricated using HoBa2Cu3O7-x and PrBa2Cu3O7-y as the superconductor and normal conductor, respectively. Their electrical characteristics are measured. The junction's normal resistance is almost comparable to that of a single PrBa2Cu3O7-y film. However, it deviates from the T-1/3 (T is temperature) law and saturates at low temperatures for junction lengths smaller than 1.0-mu-m. Superconducting characteristics obtained for this type of junction may be accompanied by this saturation of normal resistance. Nonlinear current-voltage characteristics that may reflect correlation energy in the PrBa2Cu3O7-y layer are also detected.
