对一维有机导体 (TMTTF)2SbF6 进行 13C 核磁共振 (NMR) 研究，以阐明其在基态附近的电子特性。 13C NMR 吸收线在 8 K (TN = 8 K) 以下突然变宽，证实了长程反铁磁相变。在 TN 以下，吸收线由 4 条不同的粗线组成，表明具有相应的磁结构。交错磁化强度 ρ 的振幅与 (TMTTF)2Br 相当，根据 13C NMR 线在 3 K 的分裂，约为 0.1 μB。
13C nuclear magnetic resonance (NMR) investigations were performed on the one-dimensional organic conductor (TMTTF)2SbF6 to clarify its electronic properties in the proximity of the ground states. An abrupt broadening of 13C NMR absorption lines below 8 K (TN = 8 K), confirmed a long-range antiferromagnetic phase transition. Below TN, the absorption lines are composed of four distinct broad lines, indicating a commensurate magnetic structure. The amplitude of staggered magnetization, ρ, is comparable to (TMTTF)2Br, and on the order of 0.1 μB according to the splitting of 13C NMR lines at 3 K.
