Abstract

The resistive upper critical field along the b-axis in the molecular organic superconductor (TMTSF)₂PF₆ is investigated in fields up to 17.5 T and temperatures up to T/T_c approximately 1/60, at various pressures near the border between spin density wave and metallic states. Previously, we had obtained a novel crossover where H_c2∥b exceeded both H_c2∥a (in opposition to band structure) and the Pauli paramagnetic limit (μ_oH_p≈2 T). In an optimum pressure setting reported here, it is found that the onset of superconductivity persists to 9 T (more than 4 times H_p), strongly suggestive of triplet Cooper pairing.
