Influence of Glass Coating Thickness on Magnetoimpedance Ratio in Co-Based Amorphous Microwires
The effect of glass coating thickness on the magnetoimpedance in Co-based amorphous microwires was studied. The microwires with different thickness of the glass layer were obtained by means of etching in hydrofluoric acid solution. It was observed that the value of the external mag¬netic field corresponding to the maximum of the impedance decreased with the thickness of the glass layer, whereas the magnetoimpedance ratio did not change significantly. The experimental results are interpreted in terms of changes in the radial distribution of the easy magnetization axes.
