摘要：
The influence of the spin transfer torque on a domain wall is investigated by domain wall ferromagnetic resonance micromagnetic simulations. When current is applied to the pinned domain wall in a ferromagnetic nanowire, we find two resonance frequencies of the domain wall around 2 and 7 GHz. The lower peaks represent the vibration of the whole domain wall. The higher peaks are due to the resonance frequency of the spins inside the domain wall, which show remarkable (>1.6 GHz) shifts with the spin torque. Since no domain wall displacement is involved, we can exclude the effects of the unwanted extrinsic pinning sites. (C) 2011 The Japan Society of Applied Physics
