In this work, two soft magnetic Fe73Cu1Nb3Si16B7 powder core samples were investigated. Samples were prepared by milling of amorphous Fe73Cu1Nb3Si16B7 ribbon at different temperature conditions: sample R, by milling at room temperature and sample L, by cryomilling at temperature of liquid nitrogen. Influence of applied exciting AC magnetic field with various amplitudes on the complex permeability spectra was studied. Obtained results are explained by the dynamics and relaxation phenomenon of domain walls under the influence of AC magnetic field.
