Development of Co-rich glass-coated microwires with high GMI effect

Year: 2025

Type: article

Abstract: We studied the Giant Magneto-Impedance (GMI) effect and magnetic properties of Co72Fe4B13Si11 glass-coated magnetic microwires with two different diameters. Substantially different frequency dependence of GMI effect is observed in studied microwires. A remarkable GMI ratio improvement up to 735% is observed after annealing of thicker Co-rich microwire. The observed modification of magnetic properties and GMI ratio improvement are discussed considering the internal stresses relaxation and a change in the magnetostriction coefficient sign and values after annealing.
