Abstract

In this paper, the propagation of dust-ion-acoustic DIA waves in a magnetized collisionless complex dusty plasma consisting of superthermal electrons are investigated. In the discharge plasma, the electron temperature is usually much greater than ion temperature. Thus, the electron distribution function DF, is generally nonmaxwellian, has to be modeled. For this purpose, the generalized Lorentzian \ \kappa \-DF is used to simulate the electron DF. Two types of modes fast and slow DIA modes exist in this plasma. By deriving Korteweg-de Vries KdV equation, using reductive perturbation method, both regions of solitary waves, rarefactive dark and compressive bright solitary waves, are allowed to be propagated in this plasma. Properties of DIA solitary waves are investigated numerically. How dust grains and superthermal electrons affect the sign and the magnitude of nonlinear coefficient of KdV equation is also discussed in detail. It is noted that the velocity, amplitude, and width of a DIA soliton is studied as well.
