Full textAbstract
A set of coupled nonlinear equations which governs the dynamics of low-frequency electromagnetic waves in a nonuniform electron-positron-ion magnetoplasma with non-zero ion-temper-ature-gradients is derived and solved analytically under various approximations. In the linear limit, a local dispersion relation has been derived and analyzed in several interesting limiting cases. On the other hand, a quasi-stationary solution of the mode coupling equations in the absence of collisions can be represented in the form of dipolar and vortex-chain solutions. The results of the present investigation should be useful to understand the wave phenomena in laboratory and astrophysical plasmas.
