Abstract
Peaks in the magnetoresistivity of the layered superconductor , measured in fields applied within the layers, show that the Fermi surface is extended in the interlayer direction and enable the interlayer transfer integral to be deduced. However, the quasiparticle scattering rate is such that , implying that meets the criterion used to identify interlayer incoherence. The applicability of this criterion to anisotropic materials is thus shown to be questionable.
