 de Haas-van Alphen oscillations with non-parabolic dispersions Fortin J.-Y., Audouard A. Eur. Phys. J. B (2017) ArXiv : arxiv:1702.04599 [PDF] de Haas-van Alphen oscillation spectrum of two-dimensional systems is studied for general power law energy dispersion, yielding a Fermi surface area of the form $S(E)\propto E^{\alpha}$ for a given energy E. The case $\alpha=1$ stands for the parabolic energy dispersion. It is demonstrated that the periodicity of the magnetic oscillations in inverse field can depend notably on the temperature. We evaluated analytically the Fourier spectrum of these oscillations to evidence the frequency shift and smearing of the main peak structure as the temperature increases.
