Abstract

We investigated dynamical properties of vortices in the organic superconductor κ-(BEDT-TTF) 2 Cu(NCS) 2 through resistance measurements. In the course of experiments, we found time dependent resistance oscillations with periods of 10-100sec. It indicates that the vortex system undergoes the alternating change in the state between a highly mobile state and less mobile state. This oscillation was found to appear in a wide region of the magnetic field and in a narrow region of the electric current that drives vortices.
