The influence of self-field effects on the temperature dependence of the Josephson supercurrent

Abstract

The temperature dependence of the Josephson supercurrent has been measured in a number of blob junctions formed between Nb-Zr wire and Pb-Sn solder. In favorable cases the critical current is found to increase periodically with decreasing temperature. The effect is due to the self-field generated by current flow in an asymmetric double junction. Interchanging the current and voltage leads alters the geometry of such a junction and hence alters the periodicity.
