Abstract
The behavior of the spin-lattice relaxation rate of 1H nuclei in the organic superconductor (BEDT-TTF)2Cu[N(CN)2]Br0.8Cl0.2 in the temperature interval 12–319 K is investigated. A relaxation rate maximum, which depends on the resonance frequency and is associated with thermally activated vibrations of the end ethylene groups in the BEDT-TTF molecules, is observed in the vicinity of 270 K. The relaxation rate is observed to deviate from Korringa behavior at T<100 K. These deviations can be attributed to the existence of strong antiferromagnetic spin correlations.
