Abstract
The features of the changes of the real and imaginary components of the impedance in the restructuring of the amorphous soft magnetic Co66Fe4Nb2.5Si12.5B15 wires due to direct current annealing have been revealed. The difference in the behavior of the frequency dependences of the impedance component with increasing current density annealing has been determined. The frequency range with a dominant sensitivity of the imaginary component of impedance to the structural changes in the wire compared to the real one has been detected. The results are explained on the basis of the ideas on restructuring the atomic and domain structure of the wire caused the annealing by a direct current, subject to the differences in the behavior of the components of the dynamic magnetic permeability with changing the frequency of the alternating current.
