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