Phys. Rev. Lett. 91, 056601 (2003) [4 pages]Giant Nernst Effect and Lock-In Currents at Magic Angles in (TMTSF)2PF6Received 26 February 2003; published 28 July 2003 We have measured the thermoelectric signal along the a axis in (TMTSF)2PF6 at 10 kbar as a function of the orientation of the applied magnetic field. Resonantlike Nernst signals were found with a dramatic sign change as the field was rotated through the “Lebed magic angles.” The sign change indicates that the electrical current is “locked in” to the magic angle (interchain) directions for field alignment close to, but on either side of, the magic angles. The amplitude of signals near these angles is many orders of magnitude larger than expected from conventional Boltzmann transport theory. © 2003 The American Physical Society URL:
