ResumoThe low temperature electronic properties in the organic superconductors, (TMTSF)2X, (BEDT-TTF)2X and (DMET)2X families were investigated by using 1H-NMR techniques. NMR relaxation anomalies were observed in quite different situations: In (TMTSF)2PF6, a new phase transition was observed well below the SDW transition. An anomalous enhancement of NMR relaxation was found in the superconducting states of (BEDT-TTF)2Cu(NCS)2 and β-(BEDT-TTF)2I3, suggesting novel features of the superconductivity common to the both salts. The low temperature insulating state of (DMET)2Au(CN)2 was revealed to be an SDW state. The similarity among the members of these families are discussed.
