摘要：
The effect of a spin-polarized current on magnetization dynamics is described by the Landau-Lifshitz-Gilbert (LLG) equation with the addition of Slonczewski spin-transfer term. Detailed predictions about the existence, position, and stability of magnetization self-oscillations induced by the spin-polarized current are obtained by an analytical perturbative method for different levels of current injection and externally applied field. The two cases of opposite direction of current flow are discussed.
