Abstract

Measurements of the field-dependent magnetostriction and Δ E effect in annealed, cold-drawn FeSiB amorphous wires 90-μm in diameter are reported. The results are discussed in the light of existing domain models. The field dependence of Young´s modulus and engineering magnetostriction in annealed cold-drawn Fe-based amorphous wires can be explained by the moment rotation model. Evidence from the hysteresis loops, E(H) and λ_∈( H) consistently shows that annealing first reduces the anisotropy by relieving stress. Further annealing induces surface crystallization, which increases the anisotropy and favors a domain structure with the magnetic moments aligned in a circumferential direction
