Abstract

In charge- or spin-density-wave systems, interaction between Landau levels and manybody effects produces nonlinear de Haas-van Alphen oscillations. This yields, inter alia, frequencies which are difference frequencies between ordinary oscillations with cyclotron mass equal to the sum of the ordinary masses. The new oscillations may have an amplitude as large as 10% of the ordinary ones, but they are in a new region of the spectrum where they can easily be detected. The effect is larger for weakly stable desntiy waves.
