| Zusammenfassung |
| We consider the action of the ponderomotive force
of low-frequency Alfvén waves on the distribution of the background
plasma. It is assumed that the ponderomotive force for traveling waves arises
as a result of the background inhomogeneity of medium under study. Expressions
for the ponderomotive force obtained in this paper differ from previous
analogous results. The induced magnetic moment of medium is taken into
account. It is shown that the well-known Pitayevsky's formula for the magnetic
moment is not complete. The role of the induced nonlinear thermal pressure in
the evolution of the background plasma is considered. We give estimations for
plasma displacement due to the long- and short-acting nonlinear wave
perturbations. Some discussion of the ponderomotive action of standing waves
is provided. |
