Abstract

We have found periodic oscillations in the flux flow resistance of Josephson vortices along the c-axis of Bi-2212 single crystals. The resistance oscillates periodically with increasing parallel magnetic fields above about 6 kOe, independent of the magnitude of the field and temperature. The constant period of the oscillations and the dynamical behaviors of Josephson vortices suggest vortex states and a new application to the precise magnetic field sensors in Tesla order.
