    Abstract

    The temperature dependence of the upper critical magnetic field HC2(T) in the quasi-one-dimensional molecular superconductor (TMTSF)2PF6 was determined via resistivity, for the intrachain (a), interchain (b), and interplane (c*) directions. For H along a and b, Hc2(T) exhibits pronounced positive curvature, with no sign of saturation to 0.1 K. A novel anisotropy inversion is observed, wherein Hc2 b grows larger than Hc2 a and exceeds the paramagnetic limit by more than 200%. The anomalous shape of HC2(T) is consistent with recent predictions of unconventional behavior in anisotropic superconductors, including the possibility of triplet pairing and reentrant superconductivity in very high field.
