Paper Title:
Influence of AC Driving Current on Magneto-Impedance Effect in Glass-Covered Co-Based Microwire
  Abstract

The influence of ac driving current on the frequency dependence in the range from 0.1 to 20 MHz of the giant magnetoimpedance effect (GMI) of glass-covered amorphous microwires were investigated. The dependence of GMI for a range of values of ac current (from 0.5 mA to 20 mA) flowing along the microwire has been measured in as-prepared samples. The double-peak feature is changed to the single-peak festure and the magnetic field at which the value of GMI reaches a maximum should increase with the higher the amplitude of the ac at low frequency. It was found that the change of GMI related to circular coercivity.
