Abstract
A model electron gas is studied in order to provide a microscopic justification of the Shoenberg conjecture that the harmonic content of the de Haas-van Alpen oscillations of the magnetization can properly be explained by replacing the applied field in the elementary expression for by the total induction . The model contains a current-current interaction between the electrons; and it is shown that the unscreened long-range nature of this interaction leads to a term in the low-temperature specific heat proportional to . For a gas with terrestrial densities the coefficient of this anomalous term is very small and probably beyond detection.
