Quantum magnetic oscillations of the chemical potential in superlattices and layered conductors

A theory is presented for the chemical potential oscillations in superlattices in a quantizing magnetic field applied perpendicular to the layers which takes into account the electronic miniband structure attached to eachLandau level. This miniband structure in the occupation below the Fermi energy reduces the amplitude of the chemical potential oscillations through a specific integral factor which depends on the density of states related to the electronic motion across the layers.
