Abstract :
The incommensurate spin-density wave (SDW) phase was investigated in (TMTSF)2X with the 1H NMR. A divergent peak is observed at the temperature T* well below TSDW in the temperature dependence of 1H spin-lattice relaxation rate. The frequency independent relaxation rate observed between T* and TSDW is well explained by the pinned phason mode. The power law behavior around T* suggests another phase transition at T*. It is proposed that the discommensuration structure is stabilized below T*.
