Hall resistivity in unconventional spin density wave in (TMTSF) 2PF 6 below T=4.2 K

Abstract

It is well documented that spin density wave (SDW) in (TMTSF) 2PF 6 undergoes another phase transition at T *≈4 K, though the nature of the new low temperature phase is controversial. We have shown recently that the new phase is well described in terms of unconventional SDW (USDW) which modifies the quasi-particle spectrum dramatically. In this paper, we show that the same model describes consistently the Hall resistivity observed in (TMTSF) 2PF 6.
