Abstract
Transient voltage oscillation was observed in the spin-density wave phase of (TMTSF)2AsF6. Its frequency is proportional to the non-ohmic current. In high electric field, current-field relation becomes irregular and transient oscillation diminishes. The bistability of the density-wave conductivity proposed by Littlewood is likely to be realized.
