通过脉冲 ESR 光谱研究了有机导体 (TMTTF)2PF6 的自旋间隙相变附近的自旋动力学。在基态和高温相之间的中间区域观察到弛豫时间的异常，并且与源自横向磁相互作用的电荷重新取向相关。重叠积分的计算意味着相当多的链间相互作用。横向磁相互作用在(TMTTF)2PF6 中的自旋能隙相变中起着重要作用。
The spin dynamics in the vicinity of the spin-gap phase transition for the organic conductor (TMTTF)2PF6were examined by pulsed-ESR spectroscopy. An anomaly in the relaxation time was observed in this intermediate region between the ground state and the high-temperature phase and was associated with the charge re-orientation originating in the transverse magnetic interaction. The calculation of the overlap integrals implied considerable inter-chain interactions. The transverse magnetic interaction plays an important role of the spin-gap phase transition in (TMTTF)2PF6.
