Abstract
13C-NMR relaxation rate, T1−1 and Knight shift, ΔH/H, were measured in the metallic state of the organic conductors, (DMe-DCNQI)2Cu, (DMeO-DCNQI)2Cu, and (DI-DCNQI)2Cu, the CN groups of which were substituted by 13CN. The Korringa relation, (T1T)−1/(ΔH/H)2 = (4πκB/h̵)(γn2/γe2)K(α), was found to to hold for the three compounds over the whole temperature region. The enhancement factor, K(α), is quite large (about 4.6 for the DI-salt), suggesting that these salts are highly correlated conductors.
