A double-domain model with long-range dipole–dipole interaction is proposed to investigate the self-oscillation of magnetization in nano-magnetic systems driven by self-controlled spin-polarized current. The dynamic behavior of magnetization oscillation is calculated by a modified Landau–Lifshitz–Gilbert equation in order to evaluate the effects of the long-range dipole–dipole interaction. While the self-oscillation of magnetization can be maintained substantially, several self-oscillation regions are experienced as the dipole–dipole interaction increases gradually.
► A double domain model with dipole–dipole interaction is investigated. ► Steady self-oscillation is found in this double domain model. ► The oscillation state of the system can be determined by the magnetization.
