Paper Abstract

Quasiparticle transport in superconductor/normal metal-constriction-normal metal (S1/N1-c-N2) microjunctions is investigated. Concepts of proximity effect and Andreev reflection are used in the model we propose. Attention is focused in particular on the influence of the magnetic field on zero bias anomaly (ZBA) phenomena observed in conductance spectra. Among the results, we find that the zero bias conductance is almost insensitive to the applied magnetic field in the metallic regime of a microjunction. Comparisons with experimental results are carried out.
