Abstract
We studied the influence of post-processing on magnetic properties of Fe-rich microwires and defined the routes to obtain Fe-rich cost-effective microwires with unique combination of magnetic properties allowing observation of fast and single domain wall, DW, propagation and Giant Magnetoimpedance, GMI, effect in the same microwire. By modifying the annealing conditions, we have identified the appropriate regimes allowing to achieve remarkable improvements in GMI ratio and single DW dynamics. The observed experimental results are discussed considering the radial distribution of the magnetic anisotropy and the correlation of the GMI effect and DW dynamics with hysteresis loops.
