Abstract
We present a study of the slow dynamics in the heat relaxation at very low temperature ( T < 1) in the nominally commensurate SDW compound (TMTTF)2Br, that we compare to the incommensurate SDW-(TMTSF)PF6. Instead of a broad distribution of relaxation times g( log σ ) in the PF6 salt typical 2of glassy materials, the dynamics in the Br salt reveals almost "discrete bands" in the relaxation spectrum. A saturation towards equilibrium is reached very rapidly (within ˜ 20 mn) at T ˜ 100 mK in comparison with PF6 (more than a few days for the same temperature).
