Conventional (microwave cavity) and broadband coplanar-line ferromagnetic resonance setups were used for the measurements. We found several well resolved resonance peaks. This result shows that the self-organized mask fabrication technique is able to produce high-quality samples with small dispersion of geometrical and magnetic parameters.Materials ScienceOther Condensed Mattertext
