Spin-transfer torque induced domain wall ferromagnetic resonance in nanostrips

► Spin torque induced ferromagnetic resonance of a Néel domain wall in nanostrips is studied. ► Edge modes, center modes, standing-wave modes, thickness oscillation mode and their mixed modes are found and characterized. ► Physical origin of these domain wall modes is analyzed. ► Magnetization dependence of the eigen-frequency is qualitatively explained.
