Abstract:The influence of shape, orientation, and motion patterns of magnetic domains in nanocrystalline strips with a high Ni content on soft magnetic properties was studied using normal isothermal annealing and transverse magnetic field annealing (TFA). The results indicate that TFA-10 (with 10 at. % Ni) exhibits the lowest coercivity (Hc) at 0.33 A/m and a remanence ratio (Br/Bm) of 0.2%. Moreover, more stringent conditions for the anisotropy field (Hk) are applied, and the resistance to current bias is assessed by … Show more
