Abstract

In this article, we apply impedance spectroscopy methodology to analyze the frequency response of as cast CoFeBSi wires in the 100 Hz to 300 kHz frequency range, at 10 mA ac current. Comparative evaluation performed for stressed and unstressed samples reveals major changes in the spectra of internal ac impedance of the wire. Physical concepts and problems of practical significance are discussed on the basis of the results.
