“…The highest magnitude of MI value, 58% in microwires, is reported for the as-quenched CoMnSiB microwire at about 1.5 MHz [12]. With respect to Fe-based materials, a distinct MI effect has not been achieved in any as-quenched Fe-based amorphous alloys due to their large positive magnetostriction up to now, except for the Fe 71 Zr 5 B 20 Nb 4 amorphous ribbon [14].…”

The magnetoimpedance (MI) of as-spun amorphous Co72−xFexZr8B20 (CFZB, x = 0, 2, 5, 7 at.%) alloys has been measured at a frequency ranging from 310 to 1110 kHz and a dc magnetic field between 0 to 70 Oe. The maximum MI ratio ΔZ/Z(%)max of the CFZB alloys increases with increasing frequency for each sample and decreases with the increment of Fe content at any frequency. The most drastic MI effect, the maximum value of about 90% at 1110 kHz accompanied by the field sensitivity of 18% Oe−1, is observed in CFZB without Fe. Magnetic measurements reveal that coercivity of CFZB decreases first and then increases with increasing Fe content, and the minimum value of about 1.6 Oe is obtained in the sample with x = 2 at.%. The permeability of CFZB was evaluated from quasi-static hysteresis loops, indicating that the Fe-free CFZB is of the largest permeability. Measurements on electrical resistivity suggest that the Fe-free sample possesses smaller resistivity while the sample with x = 7 at.% has a much larger resistivity compared with CFZB with 2 and 5 at.% Fe. The correlation between MI effect and magnetic properties together with electrical resistivity for the CFZB alloy is discussed in this paper.

“…Such materials can be considered as one of the most suitable materials to observe the MI effects [17]. With respect to Fe-based materials, a distinct MI effect has not been achieved in any as-quenched Fe-based amorphous alloys except for the Fe 71 Zr 5 B 20 Nb 4 ribbon [18], as the Fe-based material has a positive magnetostriction that results in a longitudinal magnetic structure in the case of tensile internal stress. Stress annealing treatment of amorphous alloys was proposed to change the stress-induced anisotropy by establishing frozen-in compression stress [19].…”

The work aims at understanding the changes in magnetic properties and the magnetoimpedance (MI) effect for the Fe 84.5 Zr 4 B 8.5 Nb 2 Cu 1 (FZBNC) nanocrystalline alloys with the annealing temperature (T a) from the microstructure point of view. The as-quenched FZBNC ribbons were annealed in a vacuum condition at selected temperatures for 20 min. The microstructures of the specimens were examined by the x-ray diffraction technique. The bcc α-Fe phase is identified from the XRD patterns. The mean grain size of the α-Fe phase (D 1) at different annealing temperatures (T a) was estimated using Scherrer's equation. The results show that D 1 for the sample annealed at 575 • C is about 20 nm, which is the smallest value among all the samples. Measurements on the MI effect reveal that the FZBNC ribbon annealed at 575 • C exhibits the most drastic MI ratio of 756% at 600 kHz accompanied by the field sensitivity of 108% Oe −1 , while a large MI effect is not observed in the sample annealed at other temperatures. The origin of the excellent MI effect is investigated in this paper.
