Abstract

<p>  The spin-wave propagation characteristics in ferromagnetic thin films with a multi-domain state were investigated by micromagnetic simulations and electrical measurements. The simulations showed that the spin waves propagated along the domain wall when excited at low frequencies. The resonance frequency shifted to a higher frequency when an external magnetic field was applied normal to the waveguide. By using a vector network analyzer, spin-wave propagation at the predicted resonance frequency was detected. The external magnetic field dependence of the resonance frequency agreed with the simulation result.</p>
