Abstract

Energy dissipation of vortices in organic superconductor κ-(BEDT-TTF)₂Cu(NCS)₂ was investigated by free torsional damping oscillation in magnetic fields up to 8 kOe in the temperature range from 1.5 K to T_c = 10 K. Damping coefficient η_sample was obtained as a function of the magnetic field H and the temperature T. For instance, Hbc-plane = 500 Oe, the η_sample has a sharp peak near 3.5 K just below irreversibility line H_irr(T). Magnetic phase defined by the η_sample peak is presented.
