Sažetak
Low-temperature thermodynamical properties of Charge(Spin)-Density Wave (CDW/SDW) systems are characterized by a glassy behaviour, somewhat, reminiscent, of structural glasses, the deep origin of disorder being here related to the random pinning of the electronic DW subsystem by impurities or defects. A remarquable property is the strong non-exponential energy relaxation following a small heat, perturbation, at T < 1 K. We report on an investigation of this effect in TaS_3 [CDW], and in (TMTSF)_2PF_6 [SDW]. A comparison is clone with the slow heat release effects observed in similar T-range in structural glasses.
