Abstract
The circular permeability μ′=μ′−jμ″ of two Fe-based soft magnetic wires with axial and transverse domains, has been determined from the measurements of impedance Z=R+jX as functions of frequency (f=10–105 Hz) and AC current amplitude (I=0.1–100 mA). From the magnetic spectra of μ′−f and μ″−f for a few circular fields (Hφ=0.4, 1.2, 4, 12, 40 A/m), we found that the sample with axial domain structure exhibits a relaxational feature, while for the one with transverse domain resonance-like spectra were observed when the circular field Hφ≥4 A/m. These results have been discussed in terms of domain structure and circular magnetization processes.
