Query: Origin of Rapid Oscillations in Low Dimensional (TMTSF)2PF6   In order to clarify the origin of the "Rapid Oscillation" (RO) in
(TMTSF)2PF6, we studied the magnetoresistance anisotropy in the Field Induced
Spin Density Wave (FISDW) phase. We have found that in the FISDW insulating
state, the Fermi surface is not totally gapped; the remaining 2D metallic
pockets are quantized in magnetic field and give rise to the RO. Decreasing
temperature does not change the size and orientation of the closed pockets,
rather, it causes depopulation of the delocalized states in favor of the
localized ones, resulting in the disappearance of the RO.
