概要
- 論文の詳細を見る
79Br NQR measurement is performed to determine the low-energy charge-transfer/dimerization fluctuations in the organic charge-transfer complex DMTTF–2,6-QBr2Cl2. With decreasing temperature, NQR line width gradually increases and the spin–lattice relaxation rate $1/T_{1}$ shows a large enhancement from the two-phonon relaxation law ($T^{7}$). This behavior is consistent with the picture that the present material is situated in the critical region of the charge-lattice-coupled quantum transition.
