Phys. Rev. Lett. 75, 4690–4693 (1995)Non-Fermi-Liquid Behavior in Transport in (TMTSF)2PF6Received 16 August 1995; published in the issue dated 18 December 1995 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 (ρa∝H⊥1/2 and ρc∝H⊥3/2). These are 2D, non-Fermi-liquid properties. © 1995 The American Physical Society URL:
