Abstract

Electric currents in a ferromagnet film produce adiabatic and nonadiabatic torques on magnetization. When the current density is sufficiently large, these torques drive the uniform magnetization into spatially and temporally chaotic motion of magnetization. We predict several key characteristics of the magnetization instability by calculating the current-induced domain wall creation, annihilation and dynamics.
