摘要
Stability analysis of the dust-acoustic mode in a magnetized three-component dusty plasma is carried out for both positively and negatively charged dust. Critical shears required to excite Kelvin-Helmholtz instability are obtained as a function of the ratio of dust charge density to ion charge density in equilibrium. It is found that the relative velocity between adjacent layers of the dust fluid should be at least equal to the dust-acoustic phase velocity in order that the instability is excited.
