- Abstract
- We have measured the current-voltage characteristics of Josephson vortex-flow branches (JVFB), corresponding to a highly dense Josephson vortex regime, in stacks of intrinsic Josephson junctions of Bi2Sr2CaCu2O8+x single crystals sandwiched between two An electrodes. We observed splitting of JVFB and switching between neighboring branches in the low current bias region in fields of about 4 T, with a spread in the resistivity of the branches. The result strongly indicates the existence of the resonance between the vortex lattice and collective transverse plasma modes, mediated by the inter-junction charging coupling incorporated with the strong inductive coupling.
