Abstract
In the charge ordering (CO) state of the quasi-one
dimensional conductors (TMTTF)2SbF6, we measured the
current-voltage relations by the pulse current method at ambient pressure.
From the measurement, we found that the conductivity is constant at low
electric field regime and increases with field above a certain field. It is
similar to the nonlinear conduction due to the ordinary density wave (DW)
sliding. However, the magnitude of the threshold electric field was larger
than that in the DW system. We will discuss the origin of the non-linear
electric conduction in the CO state of (TMTTF)2SbF6 and the
apparent similarity with it by the DW sliding.
