Oscillations of magnetoresistance in a clean hollow cylinder with a fluctuating radius
Abstract
We consider magnetic oscillations of the resistivity of a clean (mean free path l ≫ R) hollow cylinder with fluctuating (with an amplitude of fluctuations ) radius R, threaded by magnetic flux Φ. We demonstrate, that for weak fluctuations (Δ R ≪ p {F/-1}) the oscillations have a standard period 2Φ0, characteristic for oscillations in a clean system, while for Δ R ≫ p {F/-1} they become Φ0-periodic, which was expected only for dirty systems with l ≪ R. The work is motivated by observation of predominantly Φ0-periodic magnetic oscillations in very clean Bismuth wires.
