Abstract

We found the periodic oscillations in Josephson-vortex-flow resistance with the current perpendicular to the Cu-O layers of Bi₂Sr ₂CaCu₂O_8+δ. As the flow resistance is closely related to the configurations of the Josephson vortices, we have observed clear boundaries between the triangular-lattice phase and others. It is strongly suggested that the flow resistance measurements open the window to investigate magnetic phase diagram of Josephson vortices in strongly anisotropic high T_c superconductors.
