    Abstract

    We present transport and NMR studies of the normal and superconducting states of (TMTSF)2PF6 in precisely aligned magnetic fields. For the normal state the anomalous angular dependent magnetoresistance as a function of field and temperature is shown to be reasonably fit as a sum of conductivity contributions arising from interchain hopping integrals which are suppressed by a perpendicular magnetic field. In the superconducting state NMR Knight shift measurements support a triplet state as do critical fields which exceed the Pauli limit by more than a factor of four. An anomalous upward curvature in Hc2c (Perpendicular to the most conducting planes) is observed for pressures near the critical pressure which separates the SDW and superconducting phases.
