✦ Synopsis

Using a simple extension of Shiba's formula for the de Haas-van Alphen-oscillations, the influence of scattering by magnetic impurities is studied. Already for a classical spin model one obtains a minimum in the dHvA amplitudes as function of the magnetic-field, which is influenced by normal scattering. The change of this behavior for the Anderson model is studied within the Non-Crossing-Approximation, and raises questions for a comparison between experiment and theory.
