Oscillations of magnetoresistance in a clean hollow cylinder with a fluctuating radius

Miscellaneous

Abstract

We consider magnetic oscillations of the resistivity of a clean (mean free path lR) hollow cylinder with fluctuating (with an amplitude of fluctuations \(R \ll \bar R\)) radius R, threaded by magnetic flux Φ. We demonstrate, that for weak fluctuations (ΔRpF−1) the oscillations have a standard period 2Φ0, characteristic for oscillations in a clean system, while for ΔRpF−1 they become Φ0-periodic, which was expected only for dirty systems with lR. The work is motivated by observation of predominantly Φ0-periodic magnetic oscillations in very clean Bismuth wires.
