Abstract: The dynamic response of Ni80Fe20 nanowires (NWs) with controlled defects has been systematically investigated using broadband ferromagnetic resonance spectroscopy and micro focused Brillouin light scattering microscopy. We observed distinct resonance modes, corresponding to the fundamental modes of the NWs and additional modes localized in the defect region of the NWs. The resonance frequency of the defect mode is strongly dependent on the defect size. Our experimental observations are in good agreement with the micromagnetic simulations presented here. © 2014 AIP Publishing LLC.
