Tailoring of Magnetic Softness and Magnetoimpedance of Co‐Rich Microwires by Stress Annealing

physica status solidi (a), Volume 218, Issue 12, June 2021., 2021
Stress annealing allows avoiding magnetic hardening and remarkably improving the magnetic softness and giant magnetoimpedance ratio of Co‐rich microwires. Properly stress‐annealed Co‐rich microwires present almost unhysteretic loops with coercivity about 2 A m−1 and magnetic anisotropy field about 35 A m−1.
