“…λ s of FZBNC may decrease from a large positive value to a negative one passing through zero with increasing annealing temperature and the small negative magnetostriction that is closely related to a significant MI effect may be obtained in the specimen annealed at 575 • C. Moreover, after suitable thermal treatment, a relatively small effective anisotropy develops in the FZBNC ribbons, which corresponds to a large MI effect. Owing to the complex magnetic response of the domain configuration or transversal magnetic permeability [22,[44][45][46], however, the emergence of effective anisotropy is difficult to explain in detail. Furthermore, the dimensions of FZBNC must be considered.…”
