Research on double resonance peaks and abnormal frequency shift in permeability spectra of annealed FeCoB films
A FeCoB magnetic film was prepared by a magnetron sputtering method and then was divided into several small pieces for vacuum annealing at different temperatures. The dependence of the coercivity along the hard axis on the annealing temperature reveals a degeneration of softness with the growth of g...

| description | A FeCoB magnetic film was prepared by a magnetron sputtering method and then was divided into several small pieces for vacuum annealing at different temperatures. The dependence of the coercivity along the hard axis on the annealing temperature reveals a degeneration of softness with the growth of grain size when the annealing temperature is above 350
°C. In permeability spectra measurements, double resonance peaks and an abnormal positive shift in the resonance peak at higher frequency with the increase in annealing temperature are observed. The existence of two peaks is attributed to the double magnetic phases (Fe and FeCo) in the films. The positive shift in the resonance peak at higher frequency has been analyzed and ascribed to the enhanced internal stray fields with the annealing temperature. This phenomenon of positive frequency-shift is very fascinating and novel, which makes the ferromagnetic films more efficient for the applications in the noise absorbing area.
