Josephson vortex motion in a layered Bi$_{2+x}$Sr$_{2-x}$CuO$_{6+\delta}$ single crystal in parallel high magnetic fields

The dynamics of a Josephson vortex lattice in a superconducting single crystal of a one-layered high-temperature Bi2201 superconductor in parallel high magnetic fields is studied. Periodic oscillations in wide temperature and magnetic field ranges are detected in the magnetic field dependence of the flux flow resistance of Josephson vortices measured in the direction perpendicular to the layers, which is induced by the motion of the voltage vortices. The results assume that the observed oscillations are associated with the motion of a rectangular vortex lattice between the layers and matching with the transverse size of the single crystal.
