Abstract
Spin wave dispersion relations in a ferromagnetic nanowire with and without a domain wall are investigated by means of micromagnetic simulations. We confirm that the spin wave dispersion relation is shifted due to the spin wave Doppler effects, when the spin-transfer torque is applied. We also investigate the position-dependent ferromagnetic resonance spectra in the nanowire and find strong local spin wave interferences because of the formation of the standing wave due to reflections from a domain wall. It is observed that the spacing between the local spin wave constructive interferences is uniform, and it is revealed that the spacing is related with the spin wave Doppler shift.
