Abstract

Finite amplitude nonlinear ion-acoustic double layers are discussed in a magnetized plasma consisting of warm isothermal ion fluid and two Boltzmann distributed electron species by assuming the charge neutrality condition at equilibrium. The model is compatible with the evolution of negative potential double layer structures in the auroral acceleration region. The model predicts maximum electric field amplitude of about ∼ 30 mV/m, which is within the satellite measurements in the auroral acceleration region of the Earth’s magnetosphere.
