摘要：

Unconventional natures of the superconductivity in the organic superconductor, kappa-(BEDT-TTF)2Cu(NCS)2, were revealed by complex susceptibility and H-1-NMR relaxation measurements. The temperature dependence of magnetic-field penetration depth, lambda, was found to follow a power law at low temperatures, instead of an exponential behavior expected in the BCS theory. This result strongly suggests anisotropic superconductivity of gapless nature. The existence of new relaxation mechanism related to vortex dynamics in the superconducting state was confirmed.
