“…As is well known, the magnetic resonance in the GHz frequency band consists of two modes, namely natural resonance and exchange resonance. For the magnetic resonance mechanism, the complex permeability spectra ( μ ′′– f ) of all samples can be fitted with the Landau–Lifshitz–Gilbert (LLG), 62 which is expressed as eqn (16):where n is the number of peaks; is the initial susceptibilities; f is the frequency; f r is the natural resonance frequency; α is the damping coefficient. The typical curve-fitting results for the prepared samples are shown in Fig.…”
