We consider the magnetoresistance oscillation phenomena in the Bechgaard salts (Formula presented) where (Formula presented) (Formula presented) and (Formula presented) in pulsed magnetic fields to 51 T. Of particular importance is the observation of a new magnetoresistance oscillation for (Formula presented) in its quenched state. In the absence of any Fermi-surface reconstruction due to anion order at low temperatures, all three materials exhibit nonmonotonic temperature dependence of the oscillation amplitude in the spin-density-wave (SDW) state. We discuss a model where, below a characteristic temperature (Formula presented) within the SDW state, a magnetic breakdown gap opens.
