Experimental Observation of Fluxon Diffusion in Josephson Rings

Experimental Observation of Fluxon Diffusion in Josephson Rings

We present switching current measurements in niobium-aluminum oxideniobium underdamped Josephson rings. Underdamped Josephson rings display hysteretic current-voltage curves which can be characterized by their switching current, the value of applied current at which the junctions switch to the energy-gap voltage. The value of the switching current is strongly affected by temperature and by the ...
