Redistribution of magnetospheric ions under the action of Miller force

Ponderomotive redistribution of ions along geomagnetic field lines is analyzed within the frame-work of a simple model of diffusion equilibrium of a multicomponent plasma. Miller force prevails in the case of Alfvén waves. This also takes place in the case of ion-cyclotron waves at the low-frequency limit. Qualitative analysis of the equations with allowance for satellite-based data on wave intensity shows significant redistribution of magnetospheric plasma due to Miller force.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 39, No. 4, pp. 464–471, April, 1996.This paper was supported in part by the Russian Foundation for Fundamental Research (Project Code 94-05-16173a).
