【 摘 要 】

Existence of both compressive and rarefactive solitons is established in weakly relativistic but magnetized plasma with cold ions and ion-beams in presence of electron inertia. It is observed that rarefactive (compressive) solitons exist for smaller (higher) difference of electron and ion initial streaming speeds for different ion to ion-beam mass ratio and wave speed. Interestingly, the amplitude of the rarefactive solitons is seen to increase with the increase of the difference of initial streaming speeds to certain limit before turning out to be compressive after that limit.
