Abstract

The magnetization reversal process in the surface and volume areas of Co-rich glass-covered microwires has been investigated. The study has been performed in the wide series of microwires with chemical composition, geometry (thickness of glass coating) with the purpose of the tailoring of the giant magnetoimpedance effect. The comparative analysis of the magnetoelectric, magnetic, and magneto-optical experiments permits to optimise the giant magnetoimpedance ratio and elucidate the main properties of the magnetization reversal process in the different parts of the Co-rich microwire.
