    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. Previously, we had obtained a novel crossover where Hc2//b exceeded both Hc2//a, in contrast to band structure, and the Pauli paramagnetic limit μoHp≈ 2 T. Remarkably, in an optimum pressure setting reported here, it is found that the onset of superconductivity persists up to 9 T (> 4 Hp), which strongly suggests triplet Cooper pairing. Strong upward curvature with nearly diverging behaviour of the critical field also seem to suggest a field-dependent dimensional crossover, although the Hc2 enhancement is considerably more than that predicted by recent theories.
