Abstract: | Magnetoresistance in (TMTSF)2PF6 has been studied. It have been found that rapid oscillations of the magnetoresistance are absent in the metallic state and are present in the spin-ordered states solely, including both the lowest and higher order FISDW states. The spin-ordered state, which had previously been believed to be insulating, is not totally gapped; at least, at a finite temperature, there remains a vestigial Fermi surface comprising 2D metallic “pockets.” Our data agree qualitatively with the theory that considers the coexistence of two spin-density waves with two respective nesting vectors. The text was submitted by the authors in English. |
