Description
We present a 13C NMR study of the organic superconductor κ-(ET)2Cu[N(CN)2]Br in a wide temperature and pressure domain. The temperature profiles of the Knight shift and the nuclear relaxation rate in the normal phase show a striking similarity with that found in several high Tc superconductors. We suggest that nuclear relaxation is dominated by strong antiferromagnetic fluctuations due to Coulomb repulsion enhanced by nesting. From the pressure dependence of the Knight shift we estimate the U/W ratio to be of the order of unity. ((orig.))
