Abstract

All-oxide S-N-S (superconductor-normal layer-superconductor) junctions having a planar structure are fabricated and their electrical characteristics in the normal state are investigated. The superconducting electrodes are composed of HoBa2Cu3O7−x, and the normal layer is La1.5Ba1.5Cu3O7-y. Conductance characteristics are measured and their behaviors are explained by the geometrical resonance of quasiparticles. A pair potential distribution in the normal layer is estimated from the resonance structure.
