Abstract

Shubnikov-de Haas (SdH) oscillations have been investigated for the organic superconductor (methylenedithio-tetraselenafulvalene) (AuI₂)_0.436 with an incommensurate anion structure. Many SdH oscillations successively appear with increasing magnetic field, some of which are attributed to the Fermi surface reconstructed by the incommensurate anion potential. The reconstruction occurs neither by the fundamental anion periodicity q=0.436a* nor by 2q, but by 3q. The "selection rule" of the reconstructing vectors is associated with the magnitude of the incommensurate potential.
