Nonlinear ion-acoustic waves and solitons in warm-ion magnetized plasma

Finite amplitude ion-cyclotron and ion-acoustic waves and solitons propagating obliquely in a magnetized warm-ion plasma are considered using exact ion dynamics and quasi-neutrality. The effect of finite ion temperature is to decrease the amplitude of the soliton and increase its width. The behaviour of the amplitudes of ion-cyclotron and ion-acoustic waves is studied as a function of Esub(o), where Esub(o) is the slope of the potential profile at points of equilibrium particle density.
