Low temperature heterogenous dynamics in the commensurate ground state of sulfur quasi-1D compounds (TMTTF)(2)Br and (TMTTF)(2)PF6

We report on a study of the slow dynamics of the heat relaxation at very low temperature (T less than or equal to 1 K) in the nominally commensurate ground states of the sulfide compounds (TMTTF)(2)Br and (TMTTF)(2)PF6, commensurate SDW - or antiferromagnetic - and spin-Peierls, respectively. For both systems, the long-time dynamics at equilibrium shows a bimodal character, which can be analysed by slow and fast gaussian distributions g(logtau), separated by one decade in time, which can originate from defects of commensurability.
