Abstract :
We performed the measurement of 1H-NMR lineshape in the spin density wave (SDW) state of (TMTTF)2Br, in which a “commensurate” SDW state had been suggested in the recent 13C-NMR measurement. We found the most possible SDW wave-number to be (12, 14, 0) and the amplitude be 0.14μB/molecule by a precise analysis of angular dependence of 1H-NMR lineshape. The wave-number is commensurate but very close to that of the incommensurate SDW in (TMTSF)2PF6. The SDW characteristics in (TMTTF)2Br are discussed.
