Abstract:
In organic superconductor k-(BEDT-TTF)2Cu(NCS)2 [1] single crystals the logarithmic relaxation rate R corresponding to a thermally activated flux creep has a sharp maximum as a function of field B for both B perpendicular-to bc and B parallel-to bc orientations (when bc- basal plane of crystal). Contrary to the critical current, the average activation energy U(o) is isotropic and U(o) approximately 7 divided-by 10 meV for both orientations.
