Abstract: Studies of angle-dependent magnetoresistance oscillations AMRO in theinterlayer conductivity of layered metals have generally consideredsemi-classical electron transport. We consider a quantum correction to thesemi-classical conductivity that arises from what can be described as aninterlayer Cooperon. This depends on both the disorder potential within a layerand the correlations of the disorder potential between layers. We compare ourresults with existing experimental data on organic charge transfer salts thatare not explained within the standard semi-classical transport picture. Inparticular, our results may be applicable to effects that have been seen whenthe applied magnetic field is almost parallel to the conducting layers. Wepredict the presence of a peak in the resistivity as the field directionapproaches the plane of the layers. The peak can occur even when there isweakly incoherent transport between layers.
