Abstract

The structure and dynamics of a single Josephson vortex and the collective dynamics of Josephson vortices in highly anisotropic High-Tc superconductors (HTSCs) are briefly reported on the basis of the numerical simulation results. The Josephson vortex has a peculiar variation scale for the tunneling current in contrast to Abrikosov vortex. In the presence of a transport current along the c-axis, the single Josephson vortex excites wake-like electromagnetic fields behind the vortex center due to the Cherenkov radiation, while a mass of Josephson vortices move with flow lattice structures depending on the current strength. It is shown that the moving vortex lattice structures are strongly affected by the interaction with the transverse Josephson plasma modes.
