Nature of superconducting state in the new phase in (TMTSF)${}_2$PF${}_6$ under pressure

Abstract

The unusual phase has been recently observed in the organic material (TMTSF)${}_2$PF${}_6$, where superconductivity (SC) coexists with spin-density wave (SDW) in the pressure interval $p_{c1}<p<p_c$ below the first order transition into SC or normal metal phase. Assuming that the coexistence takes place on the microscopic scale, we consider the properties of the intermediate phase. We show that the new superconducting state inside SDW phase just above $p_{c1}$ must bear a triplet pairing.
