摘要：
The propagation of ion-acoustic (IA) solitary waves (SWs) is investigated in a magnetized electron-positron-ion (EPI) plasma with Cairns distributed electrons and positrons. The Korteweg-de Vries (KdV) and modified KdV (mKdV) equations are derived for the potential by employing the reductive perturbation technique (RPT) and its solitary wave (SW) solutions are analyzed. The effects of relevant plasma parameters (viz., nonthermality parameter beta, positron concentration gamma, ion thermality delta and magnetic field strength Omega) on the characteristics of IA solitary structures are discussed in detail.
