Abstract

Electron-acoustic (EA) and ion-ion-hybrid resonance (IIHR) waves, in a multi-ion-species magnetoplasma with density gradients perpendicular to the magnetic field and the direction of wave propagation are found to be drift unstable provided the inhomogeneities exceed a certain threshold. The possibility of mode conversion between the EA and the IIHR waves is examined.
