Fermi surface studies of the charge-density-wave state of the quasi-two-dimensional monophosphate tungsten bronze\({\mathrm{P}}_{4}{\mathrm{W}}_{12}{\mathrm{O}}_{44}\)

The effect of incoherent interlayer transport on the interlayer resistance of a layered metal is considered. We find that for both quasi-one-dimensional and quasi-two-dimensional Fermi liquids the angular dependence of the magnetoresistance is essentially the same for coherent and incoherent transport. Consequently, the existence of a three-dimensional Fermi surface is not necessary to explain the oscillations in the magnetoresistance that are seen in many organic conductors as the field direction is varied.
