A large nonequilibrium spin-polarized current can induce a magnetization dynamic phase (ferrodynamics) when the static uniform magnetization becomes unstable. We quantitatively determine the transport and magnetic properties of the ferrodynamic phase. The scaling exponents near the critical current are analyzed via numerical simulations. We further propose the existence of the spin electric-motive force in the ferrodynamic phase.
