- Abstract
- We observed jumps in the low-bias fluxon-flow branch of current-voltage characteristics of serially stacked intrinsic Josephson junctions (IJJs) of Bi2Sr2CaCu2O8+x (Bi-2212) single crystals in the long-junction limit. A stack of IJJs (1.5 pm wide and 17 mum long) was fabricated to be sandwiched between two An electrodes. Measurements were made in relatively high magnetic fields up to 5 T. The jumps can be explained in terms of switching between different Josephson fluxon modes in resonance with the collective plasma oscillation modes, presumably induced by both inductive and capacitive coupling.
