Abstract

It has recently been suggested that the highly anisotropic organic conductor (TMTSF)2PF6 is marginally a three-dimensional Fermi liquid which can be destabilized by a small field in the intermediate conducting b direction, Hb. This field would cause the interplane transport to become incoherent. We examine the 3D Fermi surface and find it coherent for Hb=0 and incoherent or nonexistent for small Hb. At similar Hb the magnetoresistances become power laws in the field applied perpendicular to the conducting planes (ρaH12 and ρcH32). These are 2D, non-Fermi-liquid properties.
