摘要：
We studied the effect of Joule heating on the magnetic properties and Giant Magnetoimpedance (GMI) effect of amorphous CoFe Co72Fe4B13Si11 microwires with metallic nucleus diameter around d = 25 mu m and total diameter D = 29 mu m. After Joule heating a decrease in coercivity and substantial increase in GMI ratio up to 650 % was observed. The frequency dependence of the maximum GMI ratio is evaluated: as frequency grows, we observed the onset of an additional peak on magnetic field dependencies of the GMI ratio and evaluated the frequency dependencies of said peaks for as-prepared and Joule heated samples. We discuss the observed experimental behaviors, considering the modification of the magnetic anisotropy and its spatial distribution in all samples.
