Abstract

The magnetic response of a two-dimensional layer rolled into a cylinder and located in a longitudinal magnetic field is examined. The magnetic moment of the degenerate electron gas is studied as a function of the magnetic flux. The shape of the fluctuation maxima is analyzed in detail. It is shown that at zero temperature there are breaks in each period of the change in the magnetic moment. Over this period, a plot of the magnetic moment depends strongly on the ratio of the Fermi energy to the size-confinement energy. In particular, there are no breaks for integral or semi-integral values of the square root of this ratio.
