In the present study, we address the problem of cnoidal waves (CWs) in magnetized electron-positron-ion (e-p-i) plasma with nonthermal electrons and positrons. The Korteweg-de Vries equation (KdVE) is derived using the reductive perturbation technique (RPT) and its cnoidal wave (CW) solution is analyzed. The impact of relevant plasma parameters on the characteristics of the ion-acoustic (IA) cnoidal structures are discussed in detail. The application of the present investigation is discussed.
