Alfven waves in magnetised impurity containing plasmas

Summary form only given, as follows. Linear and nonlinear wave propagation in a magnetised dusty plasma at frequencies below and of the order of the ion-cyclotron frequency is considered. It is demonstrated that the influence of the immobile dust grains leads to the considerable change of the dispersion characteristics for electromagnetic waves propagating along the uniform magnetic field, especially for small wavenumbers. The linear, nonlinear properties of the modes are discussed.
