Abstract: • FMR and spin waves resonance excitation of nano-brush are investigated. • The Fe nanowire arrays could destroy the stripe domain structure in Fe 25 Ni 75 film. • The nano-brush samples exhibit perpendicularly oriented easy axes. The magnetic heterostructures, consisting of Fe nanowire arrays (FNWs) and Fe 25 Ni 75 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 Fe 25 Ni 75 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.
