“…It has also been reported that the addition of small amounts of Mo can successfully enhance the GFA of Fe-based alloys due to its relatively large atomic radius and large negative enthalpies of mixing (∆H mix ) with the most common elements in these alloys, such as B, Si, P, and C [11,12]. The previously-reported alloy compositions include elements that promote nanocrystalline structures by proper additions of alloying elements, increasing in this way the opportunity for developing new soft magnetic amorphous and nanocrystalline alloys [13][14][15][16][17][18][19].…”

Alloying elements play an important role in adjusting the magnetic and thermal properties of Fe-based amorphous alloys. In this work, the effect of Mo addition on the thermal stability, structural evolution, and magnetic properties of Fe76Si9B10P5 metallic glass was studied. The study revealed that the substitution of a small amount of Mo (1 at.%) for Si enhances the glass-forming ability (GFA) but reduces the thermal stability of the alloy, causing a reduction of the supercooled liquid region. Substitution of up to 3 at.% Mo for Si lowers the Curie temperature from 677 to 550 K and the saturation magnetization drops from 160 to 138 Am2/kg. The structural evolution was evaluated by annealing the glassy samples at different temperatures, revealing that the crystallization proceeds in multiple steps, beginning with the formation of different iron borides (FeB, Fe2B, FeB2 and Fe23B6) followed by transformation to a mixture of more stable phases.

“…Jia added a trace amount of Mo to the Fe–Si–B–P–Cu alloys. [ 69 ] It was found that Mo can also improve the thermal stability of amorphous alloy, enlarge the temperature interval between two crystallization peaks, and facilitate the formation of α‐Fe nanocrystals, which can help to obtain good soft magnetic properties. Compared with the Fe 85 Si 2 B 8 P 4 Cu 1 Mo 1 alloy with Mo, the B s and H c of the annealed Fe 84 Si 2 B 8 P 4 Cu 1 alloy are reduced by 0.09 T and 2.4 A m −1 , respectively.…”

Fe-based amorphous and nanocrystalline alloys are widely used in transformers, electronic information, and aerospace applications due to their high saturation flux density (B s ), high permeability, low iron loss, and low coercivity (H c ). This article briefly introduces soft magnetic materials, gives an overview of the classification, preparation methods, soft magnetic properties, and applications of Fe-based amorphous and nanocrystalline alloys, and reviews the effects of elements such as Fe, Co, Ni, Si, B, P, and Nb in the alloys on the properties of Fe-based amorphous and nanocrystalline alloys such as amorphous forming ability, B s and H c . The challenges and development directions of Fe-based amorphous and nanocrystalline alloys in research are pointed out.

“…Designing an alloy with good soft magnetic properties in a one-step process is quite a difficult task. Additions of some transition metals in amounts below 1% cause very large changes in the alloy's glass-forming ability [9][10][11][12]. Appropriate selection of the chemical composition allows obtaining a nanocrystalline alloy with phases improving soft magnetic properties.…”

The magnetization process is based on bringing about a unified arrangement of the magnetic domains. During this process, there are shifts and then the rotations of the domain walls. At a later stage, domains with a direction of magnetization that do not correlate with the applied magnetic field disappear. The turnover depends on the size of the domains. For an amorphous structure, the key factors determining the size of the magnetic domains are the distance between the magnetic atoms and the possible presence of crystalline grains. The paper presents the results of research on the influence of Cu addition on the distances between magnetic atoms and the magnetization process in high magnetic fields. The structure of the alloys was studied using X-ray diffraction. The mean grain size was estimated using the Scherrer method. The magnetic properties were determined on the basis of measurements with a vibrating magnetometer. A numerical analysis of the primary magnetization curves was performed. Despite the significant reorganization of the structure, no changes in the distance between the magnetic atoms were observed, as indicated by slight changes in the D spf parameter. It was found that a small addition of Cu positively influences the improvement of the magnetic properties, in particular the reduction of the value of the coercive field.
