چکیده مقاله :
The nature of nonlinear ion acoustic waves in multicomponent magnetized dusty plasma have been investigated theoretically. Species of modeled plasma include negative dust particle, ions, electrons and positrons. Both electrons and positrons obey Fermi-Dirac distribution function. Employing reduction perturbation method, the fluid equations was solved to achieve ZK equation. Solitary and Cnoidal solution of ZK equation were considered due to number of roots of Sagdeev equation.
