“…Moreover, melt extracted microwires have a noncircular cross section, generating pinning points for the domain wall movement.

Heusler alloys present a large group of binary, [1][2][3][4][5] ternary, [6][7][8][9][10] or quaternary [11][12][13][14] compounds with a wide variety of physical properties. [15][16][17][18] Thanks to their extensive tunability [19][20][21][22] based on their chemical composition, crystal, or electronic structure, [23][24][25][26][27][28][29] they attract interest in the fundamental and application approach. [30][31][32][33][34] Particularly, spin polarization, [33,35] superconductivity, [36][37][38][39] shape memory, [40][41][42][43][44][45] or magnetocaloric behavior [28,40,[46][47][48][49][50] have triggered significant interest in the experimental and theoretical perspective.Based on the chemical composition and the resulting properties, Heusler alloys, also known as full-Heusler alloys with the stoichiometry X 2 YZ, can be divided into several groups according to their physical properties. [51] Co 2 YZ-based Heusler can be considered the leading group of materials showing high spin polarization (P) or even half metallicity (P ¼ 100%). [52][53][54][55][56][57] However, theoretical and experimental studies point to the high sensitivity of spin polarization on the structural disorder. [58] Here, the L2 1 crystalline phase exhibits the highest structural ordering, essential for achieving the required spin polarization values. [59] In contrast, while the mutual exchange of the atoms on the Y-Z position (B2 disorder) has a low influence on the spin polarization values, the X-Y or X-Y-Z disorders (D0 3 or A2, respectively) may significantly decrease spin polarization values. [55,60,61] The presented disadvantage can be solved by a suitable chemical composition or a proper method of preparation of Heusler alloys. [62,63] Stoichiometric and off-stoichiometric Ni-Mn-Z- [64][65][66] and Ni-Fe-Z-based Heusler alloys [67][68][69] are well-known magnetocaloric, shape memory, or even magnetic shape memory materials. [70,71] The mentioned Heusler alloys undergo a structural transformation from a low-temperature martensitic phase to a high-temperature austenitic phase, [51,[64][65][66][72][73][74] which may significantly influence the magnetic entropy change ΔS M and the intensity of the magnetocaloric effect. [75,76] Additionally, Heusler alloys consist of cheap elements like Ni, Fe, Mn, Co, Ga, and In, and thus may be considered low-cost counterparts for typical magnetocaloric material based on Gd, Rh, or other rare-earth elements. [77][78][79][80][81] Another advantage of the Ni-Mn-Zand Ni-Fe-Z-based Heusler alloys consists in the tunability of their structural and magnetic properties. Depending on the

“…The compelling need for low-density engineering materials is primarily driven by the need to reduce fuel consumption, which simultaneously reduces operational cost [ 4 , 5 ]. Bulk metallic glasses (BMGs), relative newcomers to the world of metal alloys, can possess a diverse array of unique properties due to their inherent glassy microstructure [ 6 , 7 , 8 ]. For example, typical low-density Al-based BMGs have occupied a special place in the material research field.…”

An interatomic potential is constructed for the ternary Al-Mg-Zn system under a proposed modified tight-binding scheme, and it is verified to be realistic. Applying this ternary potential, atomistic simulations predict an intrinsic glass formation region in the composition triangle, within which the glassy alloys are more energetically favored in comparison with their solid solution counterparts. Kinetically, the amorphization driving force of each disordered state is derived to correlate the readiness of its glass-forming ability in practice; thus, an optimal stoichiometry region is pinpointed around Al35Mg35Zn30. Furthermore, by monitoring the structural evolution for various (Al50Mg50)1−xZnx (x = 30, 50, and 70 at.%) compositions, the optimized-glass-former Al35Mg35Zn30 is characterized by both the highest degree of icosahedral ordering and the highest phase stability among the investigated compositions. In addition, the icosahedral network in Al35Mg35Zn30 exhibits a much higher cross-linking degree than that in Al25Mg25Zn50. This suggests that there is a certain correlation between the icosahedral ordering and the larger glass-forming ability of Al35Mg35Zn30. Our results have significant implications in clarifying glass formation and hierarchical atomic structures, and in designing new ternary Al-Mg-Zn glassy alloys with high GFA.

Owing to its unique atomic arrangement and electronic structure, metallic glass (MG) has been widely investigated in the field of energy storage and conversion. In the past few decades, multiple strategies have been developed to synthesize bulk and nanosized MG based materials. Here, combining the structure–activity relationship of MG with electrochemical reaction kinetics, the substantial progress of glass structures in electrocatalytic processes are highlighted, including the hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, methanol oxidation reaction, carbon dioxide reduction reaction, and nitrogen fixation. Meanwhile, applications of MG materials in energy storage devices, like supercapacitors and lithium‐ion batteries, are also introduced in detail. Finally, challenges and possibilities for reasonable design of highly‐efficient MG‐based electrode materials are proposed. The integration of high‐throughput methods, artificial intelligence technology, as well as advanced characterization techniques is fundamental to screen materials with remarkable performance. This review aims to deepen the understanding of the relationship between electronic structure and electrochemical performance, providing guidance for rational design of functional MG materials with outstanding activity, selectivity, and durability.
