摘要：

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 current-annealing technique. The connection between the magnetoimpedance response and microstructure has been studied in detail. Finally, the normalization effect on the maximum DeltaZ/Z (%) ratio achieved due to the maximum magnetic field applied during the experiment has been considered. (C) 2003 Elsevier B.V.
