Abstract :
The threshold electric field (ET) and the pinning lengths for the spin density wave (SDW) sliding were determined for (TMTSF)2AsF6 samples of various cross-sectional area (S). Contrary to large S, ET in small S samples is independent of temperature and is as large as 100mV/cm at 4.2K, We obtained the pinning length ~ 8إ in the thinnest sample, that is 4 times larger than that in thicker ones and is equal to that expected in the washboard model. Crystal size effect on the SDW dynamics is discussed.
