Incoherent interlayer transport and angular-dependent magnetoresistance oscillations in layered metals

TL;DR

This paper investigates how incoherent interlayer transport influences magnetoresistance oscillations in layered metals, showing that angular dependence remains similar to coherent cases, challenging the necessity of a 3D Fermi surface for such phenomena.

Contribution

It demonstrates that incoherent interlayer transport can produce similar angular-dependent magnetoresistance oscillations as coherent transport in layered metals.

Findings

Angular dependence of magnetoresistance is similar for coherent and incoherent transport.

A 3D Fermi surface is not required to explain observed oscillations.

Incoherent transport can account for oscillations in organic conductors.

Abstract

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.
