    Abstract

    Our recent experiments on (TMTSF)2PF6 indicate that: 1) the Knight shift along both the a and b axes remains unchanged on going through the superconducting transition (suggesting triplet superconductivity with d vector along c), 2) Hc2 is enhanced near the critical pressure for the superconducting-insulating transition by the formation of slabs parallel to the magnetic field and the anisotropy in Hc2 is determined by penetration depth rather than coherence length anisotropies, and 3) in the normal state, for fields near the Lebed magic angles the current is locked into the direction of the magic angles and there is an anomalous Nernst effect which near the magic angles is ∼200 times larger than what would be expected from Boltzmann transport.
