Abstract
We report magnetoresistance measurements to 33 T at low temperatures in dimethil(ethylendithio)tetraselenafulvalene ${(\mathrm{D}\mathrm{M}\mathrm{E}\mathrm{T}\ensuremath{-}\mathrm{T}\mathrm{S}\mathrm{e}\mathrm{F})}_{2}{\mathrm{AuCl}}_{2},$ an organic conductor with a strictly quasi-one-dimensional electronic structure at low temperatures. Magnetic field induced spin-density wave (FISDW) transitions, similar in origin to those observed in the Bechgaard salts, are investigated vs temperature and tilted magnetic field. Rapid oscillations (RO) of about 300 T are detected in this material, but only in the FISDW states. We conclude from this study that the reconstruction of a one-dimensional Fermi surface is a necessary condition for the RO phenomena to occur, and we describe the form of the resulting electronic structure.
