ABSTRACT In this work, we investigate fully nonlinear, arbitrary amplitude ion‐acoustic (IA) solitary waves in a magnetized, collisionless plasma composed of inertial warm fluid ions and non‐Maxwellian electrons obeying a deformed Kaniadakis distribution. To study these arbitrary amplitude IA solitary waves, the governing plasma model equations are reduced to a single energy‐integral using the Sagdeev pseudo‐potential method. The conditions required for the existence of IA solitary waves are examined numerically. Moreover, the regions of existence of IA solitary waves are identified in terms of key plasma parameters, including propagation obliquity, magnetic field strength, Mach number, ion temperature, and the electron deformation parameter. The influence of these parameters on the Sagdeev potential and the soliton profiles is also analyzed. This study is particularly relevant to ongoing investigations of generalized entropy frameworks in plasma physics.
