A possible mechanism for enhanced magnetic quantum oscillations in the mixed state of layered superconductors with incoherent electronic transport
Gvozdikov, V. M.; Wosnitza, J.
We present a new mechanism for the scattering rate in the mixed state of layered superconductors. This mechanism acts through the modification of the layer-stacking factor which suppresses magnetic quantum oscillations if the interlayer electron hopping is incoherent. In the superconducting state, the interlayer incoherence restores and gives a negative contribution to the interlayer quasiparticle scattering rate. The mechanism may explain recent findings of enhanced magnetic quantum-oscillation amplitudes in the superconducting state of a layered organic conductor which displays an incoherent electronic transport across the layers.
