Sažetak
We report the main features of the low frequency dielectric relaxation of the spin density wave (SDW) in (TMTSF)_2PF_6. We show that it is somewhat broader than the Debye and its shape does not change with temperature. The central relaxation time au_o is thermally activated in a manner similar to the d.c. conductivity (Delta_{fc} approx 20 K) and saturates below T_{CO} approx 1.9 K. At the same temperature the power law which gowerns the relaxation strength versus au_o behaviour ceases to be valid.
