Abstract
We have used a novel millimeter-wave magneto-optical technique to study the angle-dependence of the high- frequency conductivity of the molecular superconductor (kappa) -(BEDT-TTF)2Cu(NCS)2. The data strongly suggests that the superconducting gap has nodes directed along the b and c directions of the crystal, in agreement with recent theoretical predictions. This supports the idea that the superconductivity in (kappa) -(BEDT-TTF)2Cu(NCS)2 is d-wave in nature, and is mediated by spin fluctuations.
