Abstract The magnetic heterostructures, consisting of Fe nanowire arrays (FNWs) and Fe25Ni75 film, are prepared by combining electrochemical deposition and RF magnetron sputtering. The ferromagnetic resonance (FMR) property in the magnetic heterostructures is investigated by using frequency sweep mode and field sweep mode. The results of hysteresis loops and permeability spectra indicate that the FNWs could destroy the stripe domain structure in Fe25Ni75 film. The resonance absorption near the FMR field is excited in the heterostructures, which can be attributed to the spin non-uniform precession namely spin waves resonance excitation.
