    Abstract

    The resistive upper critical field along the b axis (Hc2∥b) in (TMTSF)2PF6 is investigated in detail in fields to 17.5 T and temperatures to T/Tc∼1/60, at various pressures near the border between spin-density wave and metallic states. Remarkably, in an optimum pressure setting reported here, it is found that the onset of superconductivity persists up to 9 T (>4Hp), which strongly suggests triplet Cooper pairing. Strong upward curvature with nearly diverging behavior of the critical field seems to suggest a field-dependent dimensional crossover, although the Hc2 enhancement is considerably more than that predicted by recent theories.
