概要
- 論文の詳細を見る
ESR and ^1H-NMR investigations of the quasi-one-dimensional organic conductors, (BDTFP)_2X(PhCl)_<0.5> (X = PF_6, AsF_6), were carried out. The low-temperature physical properties of the title compounds are quite different from each other, although those at R.T. are very similar. The PF_6 salt undergoes a spin-singlet transition around 170 K. On the other hand, the AsF_6 salt shows a discontinuous transition of first order around 230 K, in association with an abrupt jump in the spin susceptibility. The AsF_6 salt shows spin-gap behavior below 50 K, but it undergoes an antiferromagnetic transition at 14 K. The low-temperature electronic states of the title compounds are discussed by microscopic point of view.
