ABSTRACT
The oblique propagation of arbitrary ion acoustic solitary waves (IASWs) in magnetized electron-positron-ion plasmas is investigated by employing Sagdeev pseudopotential approach. Ions are assumed to be adiabatic having anisotropic thermal pressure. Electrons and positrons considered isothermal, following Maxwellian distribution. In terms electrostatic potential, potential function obtained analyzed numerically the context relevant plasma configuration parameters. existence region pulses defined accurately. It how several parameters, such as positron concentration, parallel, perpendicular pressure affect soliton characteristics.
