Influence of DC Joule-heating treatment on magnetoimpedance effect in amorphous Co64Fe21B15 alloy

The influence of DC Joule-heating treatment on magnetoimpedance response in Co64Fe21B15 ribbons has been studied. Monitoring of electrical resistance during the thermal treatment, hysteresis loops measurements, X-ray diffraction (XRD) and Mossbauer spectroscopy were used to study the structural chan...

Description
Summary:The influence of DC Joule-heating treatment on magnetoimpedance response in Co64Fe21B15 ribbons has been studied. Monitoring of electrical resistance during the thermal treatment, hysteresis loops measurements, X-ray diffraction (XRD) and Mossbauer spectroscopy were used to study the structural changes induced by the currentannealing technique. The connection between the magnetoimpedance response and microstructure has been studied in detail. Finally, the normalization effect on the maximum *DZ/Z (%) ratio achieved due to the maximum magnetic field applied during the experiment has been considered.
