NMR Relaxation Time of the Anisotropic Superconducting State in Quasi-One-Dimensional Systems

抄録

The NMR relaxation rate, T₁⁻¹, is calculated for the various possible types of anisotropic superconductivity in quasi-one-dimensional systems proposed by the present authors for the (TMTSF)₂X family. A comparison with recent experiment by Takigawa, Yasuoka and Saito on (TMTSF)₂ClO₄ indicates that the superconductivity of this family belongs to a novel type with the order parameter having lines of zeros on the Fermi surface.
