However, its microstructure control with a high soft phase fraction is of great challenge. Here, we report a strategy to fabricate SmCo/α-Fe(Co) nanocomposite bulk magnets with a soft phase content of over 30 wt%. The resultant (SmCo₇ + SmCo₃)/α-Fe(Co) nanostructure exhibits high soft phase content (31 wt%), small grain size (∼9 nm), and strong texture of the two hard phases (SmCo₇: <em>I</em>₍₀₀₂₎/<em>I</em>₍₁₁₁₎ = 0.96, SmCo₃: <em>I</em>₍₀₀<em>₁₂</em>₎/<em>I</em>₍₁₁₆₎ = 0.77). The good microstructure results in a large coercivity (<em>H</em>_ci = 4.2 kOe) and a high remanence ratio (<em>M</em>_r/<em>M</em>_s = 0.93), achieving an impressive energy product of 28.3 MGOe. This value is 51% larger than that of the SmCo₇/α-Fe(Co) nanocomposite magnets (18.7 MGOe) and 66% higher than that of the highest reported value (17 MGOe) of the SmCo₃/Fe(Co) nanocomposite magnets. The purposeful introduction of Fe, Cu, and Zr elements in the SmCo hard magnetic phase precursor allows the Fe and Co atoms to diffuse from the hard phase to the soft phase, thus obtaining a high soft phase fraction. These results represent an important step to novel SmCo nanocomposite magnets with excellent performance.</div></div>","PeriodicalId":366,"journal":{"name":"Journal of Magnetism and Magnetic Materials","volume":"629 ","pages":"Article 173269"},"PeriodicalIF":2.5,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the inductor made by carbonyl iron powders, the inductor with 30 wt% submicron FeNi particles can obtain better DC bias performance (saturation current increased by 9.8 %) and lower loss (the quality factor increased from 13 to 20, an increase of 53.8 %). The influence of submicron FeNi particles on the magnetic loss of soft magnetic composites was discussed from the view of microstructure and dynamic magnetization process. With the decrease of particle size, the number of magnetic domains in particles decrease and the size become finer, which leads to the decrease of domain wall resonance component and the enhancement of spin rotation component during dynamic magnetization. The reduction of domain wall displacement and domain refinement reduce hysteresis loss and excess loss. The small size of submicron FeNi particles also lead to low eddy current loss.

Antimony telluride (Sb₂Te₃) stands out for its remarkable thermoelectric, optical, and topological properties but faces limitations like moderate thermoelectric efficiency and high thermal conductivity. This study investigates the impact of chromium (Cr) doping on Sb₂Te₃’s optoelectronic, magnetic, thermoelectric, and mechanical properties using DFT + U calculations. Cr incorporation significantly alters the electronic structure, inducing bandgap narrowing and pronounced spin splitting. The resulting spin-dependent band shifts enhance electrical conductivity while preserving a substantial Seebeck coefficient. DOS analyses reveal localized Cr-d states near the Fermi level, increasing carrier concentration and spin polarization. Magnetic analyses show that Cr’s large magnetic moment (3.77053 μB) drives ferromagnetic ordering, with a total moment of 4.00016 μB, highlighting potential for spintronic devices and quantum computing via the quantum anomalous Hall effect (QAHE). Thermoelectric evaluations demonstrate improved ZT values due to enhanced electrical conductivity and reduced lattice thermal conductivity from phonon scattering. The Seebeck coefficient remains favorable across temperatures, with spin-dependent variations suggesting applications in spin-caloritronics. Mechanical assessments reveal that Cr doping enhances Sb₂Te₃’s structural stability and mechanical robustness. Elastic constants (C₁₁, C₃₃) increase upon doping, reflecting improved resistance to uniaxial deformation. Enhanced shear constants (C₄₄, C₆₆) indicate better shear resistance, while bulk modulus (40.2 GPa), shear modulus (25.6 GPa), and Young’s modulus (64.8 GPa) confirm increased stiffness. The Poisson’s ratio (0.28) suggests that the doped material retains sufficient ductility for practical applications, and the improved Vickers hardness (2.9 GPa) signifies better wear resistance. These mechanical improvements ensure the material’s suitability for devices subjected to mechanical stress. Optically, Cr doping increases absorption in the visible and infrared regions, making the material suitable for solar cells, infrared detectors, and photonic devices. Modified dielectric and energy loss functions reflect improved light-matter interactions and reduced reflectivity. Overall, Cr-doped Sb₂Te₃ exhibits a synergistic enhancement of its multifunctional properties, including electronic, magnetic, thermoelectric, mechanical, and optical characteristics. These comprehensive improvements position it as a strong candidate for spintronics, thermoelectric generators, and optoelectronic technologies, laying the groundwork for future experimental validation and device integration.</div></div>","PeriodicalId":366,"journal":{"name":"Journal of Magnetism and Magnetic Materials","volume":"629 ","pages":"Article 173258"},"PeriodicalIF":2.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144263262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
