中文摘要	We report the nonautonomous domain wall motion in ferromagnetic nanowire driven by spin-polarized current and magnetic field. Our results expatiate the major formation of domain wall velocity which comes from two parts: the longitudinal external field along the easy axis and the coherent domain wall rotation velocity. A critical condition is obtained analytically. Below the critical value, the domain wall rotation stops finally and domain wall velocity is proportional to the longitudinal external field. Above the critical value, the domain wall open out the novel nonautonomous helical motion characterized by the coherent rotation without any distortion. The domain wall velocity can be arbitrarily large for the linear proportion to longitudinal field strength.
