摘要
Large time-dependence effects have been measured below 1 K in the specific heat of the spin-density-wave (SDW) compound (TMTSF)(2)PF6, well below its glass transition temperature at 3.5 K. These effects indicate that most of the low-energy excitations characteristic of the disordered nature of the SDW subsystem are decoupled from the phonon bath for t greater than or similar to 1 s. A comparison is done with the related slow heat release observed over similar long time scales (up to 10(4)-10(5) s) in structurally disordered materials.
