Abstract
We report a study of the transverse magnetoresistance in the spin-dens ity-wave state of the organic conductor (TMTSF)2NO3 at ambient pressur e, 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 decreas es when the temperature departs from 4.2 K. This is tentatively interp reted within the framework of magnetic breakthrough and quantum interf erences.
