Abstract:
Processing of the Co-rich glass-coated microwire by Joule-heating allows considerable improvement of magnetic softness and Giant Magneto-Impedance (GMI) effect. At optimal Joule heating conditions, we observed GMI ratio up to 650%, low magnetic anisotropy field of about 25 A/m and coercivity of about 2 A/m. Observed experimental dependencies are discussed considering various factors affecting the magnetic properties of studied microwire upon Joule heating: induced magnetic anisotropy, internal stresses relaxation and radial distribution of magnetic anisotropy.
