Abstract

The permeability spectra has been measured in as-quenched (co_0.94Fe_0.06)_72.5Si_12.5 B₁₅ amorphous wire as a function of dc-biased current, I_b. Two relaxations of permeability spectra are revealed in 4 and 52 kHz regions, indicating that different magnetization mechanisms are involved in each frequency region. As the dc-biased current I_b increases, the value of spectra curve at 52 kHz monotonously decreases due to the decrease of core domains by I_b. However, the value of the spectra curve at 4 kHz increases with I_b up to 4.25 mA and then decreases with further increasing I_b.
