Analyses on multiple resonance behaviors and microwave reflection loss in magnetic Co microflowers

Abstract: Triple dielectric and magnetic resonance behaviors have been observed and studied in Co microflowers within a frequency range of 0.1-18.0 GHz. To characterize such triple-resonance behaviors, the dielectric resonance was resolved by fitting the Lorentzian dispersion law, magnetic resonance spectra was fitted by the Landau-Lifshitz-Gilbert equation. It is demonstrated that our fitted and calculated resonance frequencies agree well with the experimental data. Dielectric resonance in permittivity was due to the d… Show more

“…In general, magnetic loss is reported to be dependent of magnetic hysteresis, domain-wall resonance, eddy current effect, exchange resonance and natural resonance. Considering the weakly applied magnetization field during the electromagnetic measurement38, magnetic hysteresis could be neglected. The domain-wall resonance is reported to takes place in the MHz range, and can also be excluded39.…”
