What does this research mean for the field?

DC Joule heating at an optimal current of 1 A enhances the magnetoimpedance effect and lowers electrical resistivity in Fe- and Co-based melt-spun ribbons through nanocrystal formation and stress relaxation, whereas higher annealing currents degrade these properties. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the influence of direct-current (DC) Joule annealing on the magnetoimpedance response and electrical properties of Fe- and Co-based melt-spun alloy ribbons.
Synthesized Fe72Si10Cu1Nb2B15, Co72Ni5Si5Cu1Nb2B15, and Co77Si5Cu1Nb2B15 ribbons using melt spinning.
Subjected ribbon samples to DC Joule annealing at current levels of 1 A and 1.5 A.
Characterized magnetoimpedance (MI) effects, magnetic anisotropy, effective permeability, and DC electrical resistivity across as-quenched and annealed states.
Joule annealing at 1 A produced higher MI values than the as-quenched state for all compositions due to surface nanocrystallization in Fe-based ribbons and stress relaxation in Co-based ribbons.
Increasing the annealing current to 1.5 A reduced MI values relative to 1 A across all alloys due to lower effective permeability and domain pinning from localized heated regions that induced large magnetic anisotropy.
DC electrical resistivity decreased across all three ribbon types after 1 A annealing due to atomic ordering and reduced electron scattering from uniformly distributed nanocrystals in the amorphous matrix.
