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.

Journal of Sensors, Volume 2021, Issue 1, 2021., 2021 Concentrated stresses and residual ones are critical for the metal structures’ health, because they can cause microcracks that require emergency maintenance or can result in potential accidents. Therefore, an accurate approach to the measurement of stresses is key for ensuring the health of metal structures.
