Nonlinear propagation of magnetoacoustic waves in magnetized, collisionless, warm bi-ion plasmas with positive and negative ions of different masses and charge states are investigated. The two-fluid model is used here. Using reductive perturbation technique, the Korteweg-de Vries equation is derived as nonlinear dispersion relation, and its solution for the magnetoacoustic solitons propagating in the direction perpendicular to the external magnetic field is obtained. Using experimental values for the plasma parameters, magnetoacoustic soliton structures for K-fullerene plasma are illustrated along with some other useful alkali-fullerene plasmas.

碱性富勒烯等离子体中的磁声孤子

研究了具有不同质量和电荷状态的正负离子的磁化,无碰撞,温暖的双离子等离子体中磁声波的非线性传播。这里使用两流体模型。利用还原摄动技术,将Korteweg-de Vries方程推导为非线性色散关系,得到其在垂直于外部磁场方向传播的磁声孤子的解。使用等离子体参数的实验值,说明了K-富勒烯等离子体的磁声孤子结构以及其他一些有用的碱富勒烯等离子体。
