Unconventional spin-density wave in Bechgaard salt (TMTSF)2NO3
Among many Bechgaard salts, (TMTSF)2NO3 exhibits very anomalous low temperature properties. Unlike conventional spin density wave (SDW), (TMTSF)2NO3 undergoes the SDW transition at TSDW approx 9.5K and the low temperature quasiparticle excitations are gapless. Also, it is known that (TMTSF)2NO3 does not exhibit superconductivity even under pressure, while FISDW is found in (TMTSF)2NO3 only for P=8.5kbar and B>20T. Here we shall show that both the angle dependent magnetoresistance data and the nonlinear Hall resistance of (TMTSF)2NO3 at ambient pressure are interpreted satisfactory in terms of unconventional spin density wave (USDW). Based on these facts, we propose a new phase diagram for Bechgaards salts.
