Nonlinear ion acoustic waves using a fluid model in cylindrical coordinates for the propagation parallel to the magnetic field are investigated in a low-beta magnetized plasma. It is found that beside the existence of smooth regular solitons, cusp solitons also exist in plasmas when certain plasma conditions are satisfied. Characteristics of bipolar electric field solitary structures are also studied corresponding to the smooth regular solitons. Theoretical results agree with observations.
