Abstract

The obliquely propagating ion acoustic (IA) double-layers are investigated in a magnetized two population electron plasmas. The extended Korteweg–de Vries equation is derived by using the reductive perturbation technique. The effect of obliqueness (l z ) and magnitude of the external magnetic field (ω ci ) , as well as the electron number density (β) on the double-layer profile, is studied, and then the ranges of parameters for which the double-layers exist are investigated in detail. We found that the combined effects of l z , ω ci , and β significantly modify the basic properties (viz. amplitude and width) of the IA double-layers.
