Under various amplitude of AC magnetic fields domain wall motion is the main mechanism in the magnetization process. This includes domain wall bulging and domain wall displacing. In this paper complex permeability-frequency spectra of (Fe1−xCox)73.5Cu1Nb3Si13.5B9 (x=0,0.5x=0,0.5) nanocrystalline alloys were measured as a function of the AC magnetic field, ranging from 0.001 to 0.04 Oe. Obvious changes have been found in complex permeability spectra for alloy x=0x=0 with the change of the amplitude of AC magnetic field, but variation of AC magnetic field has little effect on complex permeability spectra for alloy x=0.5x=0.5. This is attributed to the increased pinning field after substitution of Fe with Co in Fe73.5Cu1Nb3Si13.5B9 nanaocrystalline alloy.
