中文摘要	The complex conductivity of the spin-density wave (SDW) in (TMTSF)(2)AsF6 was measured between 1 kHz to 10 MHz under various d.c. bias in the temperature range from 1.7 K to 6 K. For the data without d.c. bias, the scaling relation between the a.c. SDW conductivity and the quasi-particle conductivity was demonstrated. For the first measurement of the d.c. bias dependence of the complex conductivity, the real part of the conductivity increased and the imaginary part decreased rapidly above the threshold field of the nonlinear conduction. In addition, an interference structure was observed in the d.c. bias dependence of the dielectric function. This structure became obscure with increasing frequency. We suggest that this behavior can be understood in terms of the crossover from screened SDW response to unscreened SDW response. These observations suggest that the charge dynamics of the SDW in the sliding state are very similar to those of the CDW and can be treated as for a classical deformable charged object.
