Influence of Landau Level Broadening on the de Haas-van Alphen Effect

Abstract
Dingle's treatment of the influence of Landau level broadening on the de Haas-van Alphen effect is extended by the method of Lifshitz and Kosevich to include a Fermi surface of arbitrary shape. It is shown that a momentum- or energy-dependent linewidth can influence the period, phase, and amplitude of the magnetization oscillations, although crude estimates indicate that in many cases the effects would be quite small.
