摘要：

We report a study of the transverse magnetoresistance in the spin-density-wave state of the organic conductor (TMTSF)2NO3 at ambient pressure, in fields up to 37 T. For field along the lowest conductivity axis (c*), two series of quantum oscillations, with temperature-independent frequencies of 63 T and 248 T, respectively, are observed in the 2-12 K temperature range. The oscillation amplitude of both series decreases when the temperature departs from 4.2 K. This is tentatively interpreted within the framework of magnetic breakthrough and quantum interferences.
