“…As it was shown in [3], the highest Curie temperature of the amorphous matrix, in the Fe 86−x Ni x Zr 7 Cu 1 B 6 alloys, belongs to x = 43. Such concentration of iron and nickel, respectively, predicts the most intensive influence of the ferromagnetic atom pair reorientation (directional ordering) on the soft magnetic properties of investigated alloys, in accordance with [4,5].…”

Development of the atomic directional ordering in the Fe43Ni43Zr7Cu1B6 alloy, during its conventional the same as after transverse magnetic field annealing, was experimentally studied by the amplitude dependence of susceptibility and hysteresis loops measurements, respectively. Diffusion processes of the mobile atoms caused perminvar effect, decrease of the initial susceptibility, increase of the critical field, and linear shape of the hysteresis loop. Uniaxial magnetic anisotropy, created during magnetic field annealing of the FeNiZrCuB alloy, was confirmed also by observation of the surface domain structure.

“…The lowest coercivity value was found for the LF-annealed, thermally relaxed amorphous sample, where H C reached ∼ 0.7 A/m. Sheared loops with good eld linearity were achieved after TF -annealing similarly as in [4,5]. Figure 1 shows that the GMI characteristics exhibit single or double peak structure depending on the orientation of external magnetic eld applied during the heat treatment.…”

Magnetoimpedance Effect in Field Annealed (FeNi)_{78}Nb_{7}B_{15} Amorphous and Nanocrystalline Bilayer Ribbons

The inuence of the magnetic eld annealing on the magnetoimpedance eect has been investigated in rapidly quenched (Fe0.5Ni0.5)78Nb7B15 monolayer and bilayer thin ribbons. The highest impedance ratio value (∆Z/Z)max = 72% and the maximum eld sensitivity ηmax = 12 %/Oe was obtained in the bilayer ribbon, annealed under longitudinal magnetic eld at 773 K that exhibited nanocrystalline structure. The higher values of (∆Z/Z)max in bilayer ribbons, as compared to their monolayer counterparts, are attributed to the increased ratio of their thickness to the penetration depth.

“…Microstructural features such as preferred crystalline orientation, elongated and/or textured precipitates or directional pair ordering are attributed to the * corresponding author; e-mail: ipetryshynets@saske.sk main origins for anisotropy in various polycrystalline or multiphase magnetic materials [3]. Our field annealing experiments in Fe-based amorphous and nanocrystalline alloy systems have revealed that application of low and medium static magnetic field (< 1 T) in longitudinal direction to the ribbon axis can result in drastic reduction of coercive field [4,5]. Here, the improvement of soft magnetic behavior is explained in terms of magnetic atoms pair ordering mechanism [6].…”

In this work, we report on the effects of high static magnetic field on the formation of desirable crystallographic orientation of grains ("rotating" cube) during the primary recrystallization of non-oriented steels. Vacuum degassed non-oriented steel with the silicon content about 1 wt% was taken from industrial line after final cold rolling with 80% of deformation and then it was subjected to the laboratory annealing at temperature of primary recrystallization. Whole annealing process was carried with and without the applied external magnetic field of 14 T. The analysis of crystallographic orientation of experimental material was studied by electron backscattered diffraction technique. The microstructural and textural observations have shown a small difference in average grain size between samples annealed with and without magnetic field as well as increase of the "rotating" Cube component and decrease of the intensity of deformation texture by application of magnetic field. The magnetic measurements show that the coercivity value of the sample annealed in the magnetic field of 14 T can be reduced by approximately 3% in comparison with sample annealed under the zero field conditions.
