The magnetoquantum oscillations in NbSe3 show frequency shifts and beat structures due to interaction with the pinned charge-density-wave (CDW) configuration. Measurements in magnetic fields up to 220 kG indicate that local deformations of the pinned CDW cause extremal area changes in small lens-shaped sections of normal Fermi surface (FS). Calculations of magnetic breakdown (MB) to the open nested sections of FS with a distribution of areas at the MB junctions can explain the data.
