It shows the microaddition of Bi and In could facilitate the formation of α-Fe nanocrystals and reduce the growth activation energy, due to their positive mixing enthalpies (ΔHmix) with Fe and rapid diffusion of their atoms. The promoting effects of In and Bi (especially In) addition on α-Fe precipitation increased the crystallization volume fraction (vcr) and thus enhanced the magnetic flux density (Bs) of nanocrystalline alloys.

The present results indicate that microaddtion of low melting point element possessing positive mixing enthalpies with Fe could significantly improve the magnetic properties of the nanocrystalline alloys, which possess great potentials of application in high frequency electronic apparatus.

Three radiation-induced hole-center paramagnetic defects were identified, though simulating the broad electron-center signals was challenging. A prominent Fe3+ resonance line (g∼ 4.28) was simulated using a rhombic spin Hamiltonian, and γ-irradiation caused a shift in the Fe3+ gisovalue. While the axial zero-field-splitting (ZFS) parameter (D) remained stable, the rhombic ZFS parameter (E) decreased with increasing radiation, increasing rhombicity (λ= |E/D|). This suggests that radiation-induced defects distort the Fe3+ sites' electronic environment in the glass network.

The thermal behaviour, phase composition, micromorphology, and network structure of the glasses were investigated, and it was observed that the crystal structure, crystallinity, and microscopic morphology of the glass-ceramics have a significant effect on the photocatalytic activity. XRD and SEM results confirm the precipitation of the monoclinic Bi2MoO6 and orthorhombic Bi2WO6 crystals, which are nano-spherical and 3D dumbbell-like structures, respectively. The prepared glass-ceramics exhibit a strong absorption in the UV–Vis region. The photocatalytic activity of the Bi2MO6 (M=Mo, W) glass-ceramic powders is evaluated by methylene blue dye under UV irradiation. Under the same conditions, the Bi2WO6 glass-ceramic powders exhibit a higher photocatalytic activity than the Bi2MoO6 glass-ceramic powders. The Bi2WO6 glass-ceramic powders achieve a 73% degradation of methylene blue dye after 150 min of irradiation. The difference in photocatalytic activity is mainly related to the crystal structure, crystallinity, and micromorphology of the glass-ceramics.

This structural complexity is further pronounced in compositions such as FeMCuSiB (M = Nb, Mo, W and Ta), which incorporate elements with varying atomic radii and valencies. The Young's modulus of structures generated using traditional methods, such as melt-quenching and random packing, shows poor agreement with experimental data. In this study, we employ hybrid methods for generating the structures, which involve randomly packing elements without overlap, followed by thermalization at room temperature using Ab-initio Molecular Dynamics simulations. The Young's modulus evaluated from these structures aligns well with values measured using Dynamic Mechanical Analysis. Additionally, we utilize these structures to determine other elastic moduli including the bulk modulus and tetragonal shear modulus and find that the obtained values are consistent with the expected range for these compounds. We attribute the improved accuracy to a more representative approximation of the amorphous structure and the direct application of energy-strain relationships, rather than stress-strain relationships, for elastic moduli determination.
