Abstract
The transverse magnetoresistance of the Bechgaard salt (TMTSF)(2)PF6 for va rious pressures has been measured, with the field up to 27 T parallel to th e lowest conductivity direction c*. We describe the pressure dependence of a single series of rapid oscillations (RO) in the magnetoresistance inside the spin-density-wave (SDW) state. The oscillation frequency increases from 270 Tat 0.21 GPa up to 310 T at 0.77GPa. A possible mechanism of the RO is discussed from the viewpoint of the commensurability between the SDW wavel ength and the crystalline lattice.
