Anisotropic Superconductivity and NMR Relaxation Rate in Organic Superconductors

  • Yasumasa Hasegawa
  • Hidetoshi Fukuyama


Possible types of superconductivity in both quasi-one- and quasi-two-dimensional systems are examined theoretically. The NMR relaxation rate, T 1 -1 , is calculated for each state. The comparison with the experiment in (TMTSF)2C104, which is the quasi-one-dimensional organic superconductor, indicates that the superconductivity of this family has lines of zeros of the gap on the Fermi surface. It is suggested that β-(BEDT-TTF)2X can be in the triplet state.
