| Popis: | The influence of the glass-cover thickness on the magnetoimpedance of amorphous cobalt-based microwires is studied. Microwires with different values of the glass thickness were obtained by etching off the glass cover with fluorhydric acid. It was found that, as the cover thickness decreases, the magnetoimpedance ratio does not substantially change, while the intensity of the external magnetic field in which the impedance attains its maximum also decreases. The experimental results are explained using a model taking into account changes in the radial distribution of the anisotropy axes with a decrease in the glass-cover thickness. |
