要約(英語): Fe flake was fabricated by ball-milling, and frequency dependences of permeability and noise suppression of resin composite with Fe flake were investigated. The aspect ratio of Fe flake increased with increasing ball-milling time (tm), and the highest aspect ratio was 43 after ball-milling for tm=12 h. Frequency dependence of imaginary part of complex permeability for resin composite with Fe flake had two inflection points (f1, f2) related to the domain-wall resonance and natural resonance. Noise suppression properties of resin composite with Fe flake was higher than that of resin composite with spherical powder, and the noise suppression property had a peak close to f2.
