Description
The authors report 13C NMR spin-lattice relaxation rates 1/T1 and Knight shifts KS in the quasi-two-dimensional organic superconductor κ-(ET)2Cu[N(CN)2]Br (Tc=11.6 K), for an aligned single crystal. The normal-state behavior is reminiscent of the high-Tc cuprates, in which antiferromagnetic fluctuations and spin-gap behavior dominate. In the superconducting state, the data rule out the BCS electron-phonon mechanism as the source of the superconductivity, but support an unconventional pairing state with possible nodes in the gap function
