Electric Field Effects on Quasi 1D Organic Conductor (TMTSF)$_{2}$PF$_{6}$

We present a study of the behavior of the 1-D organic conductor, (TMTSF)$_{2}$PF$_{6}$, under electric field. We observed a dependence of the conductivity, critical temperature (at which the spin density wave effect occurs, T$_{SDW})$, and magnetoresistance with the applied electric field. The conductance of the sample in the low temperature range (less than T$_{SDW}$ = 12 K) is observed to be increasing with the applied electric field. The T$_{SDW}$ appears to decrease with increasing electric field. The magnetoresistance behavior changes from positive to negative when higher electric field is applied. All these three dependences are ambipolar.
