Abstract:
We provide our attempts to improve the Giant Magneto-Impedance (GMI) effect and magnetic softness Co-rich glass-coated magnetic microwires by annealing. We studied the effect of annealing on the hysteresis loops and the GMI ratio of Co-rich microwires. A remarkable GMI ratio improvement up to 735% is observed after annealing of Co-rich microwires at appropriate conditions. The observed magnetic softening and GMI ratio improvement are discussed considering the internal stresses relaxation and a change in the magnetostriction coefficient sign and values after annealing.
