Abstract
An attempt has been made to find out the effects
of trapped electrons in dust-ion-acoustic solitary
waves in magnetized multi-ion plasmas, as in most space
plasmas, the hot electrons follow the trapped/vortex-like
distribution. To do so, we have derived modified
Zakharov–Kuznetsov equation using reductive perturbation
method and its solution. A small-k perturbation technique
was employed to find out the instability criterion and
growth rate of such a wave.
