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