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 Alphen oscillations of the magnetization M can properly be explained by replacing the applied field H in the elementary expression for MH by the total induction B H M. 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 T ln T. For a gas with terrestrial densities the coefficient of this anomalous term is very small and probably beyond detection. Author
