Résumé

We have studied the microwave surface resistance of κ-(BEDT-TTF)2Cu(NCS)2 under the application of a magnetic field (up to 10 Tesla) oriented perpendicular and parallel to the highly conducting plane. In the superconducting state the resistance is highly anisotropic and free of any hysteritic effects; we analyze the data in terms of dissipation due to vortex motion. The resulting temperature profile of the critical field Hc2(T) for the perpendicular direction shows, in contrast to previous result, a downward curvature.
