Summary: The effects of hydrogen implantation on the magnetic properties of amorphous Fe88.4Zr11.6Hx films were studied, showing that the Curie temperature increases and coercivity decreases with increasing hydrogen content. The local random anisotropy constant decreases with higher hydrogen concentration, and the ferromagnetic correlation length increases significantly. The local anisotropy extracted from coercivity fits well with the results obtained using random magnetic anisotropy approach.

Summary: Soft magnetic materials are crucial for the magnetic cores in motors and generators. Understanding the mechanism of energy loss under oscillating magnetic fields is important for improving energy efficiency. Micromagnetic simulations revealed that the magnetic energy of moving domain walls in nanocrystalline soft magnetic materials dissipates through magnetostriction, thus providing guidance for the design of highly energy-efficient materials.

Summary: The compositional effect of magneto-elastic and magnetostriction properties of Fe-rich nanocrystalline alloys were studied by systematically varying the Fe and P content. The as-quenched and nanocrystalline alloys exhibited large positive magnetostriction and showed strong compositional dependence to the P content. The unusually large magnetostriction of optimally annealed samples was attributed to the low crystal volume fraction of nano-crystalline ribbons.

Summary: This study reviewed literature to determine the density of amorphous soft magnetic alloys and found it can be accurately described by a regression function. The change in density during amorphization and subsequent nanocrystallization was estimated to be between 0.5% and 3%, depending on the alloy composition. The difference in density between a crystalline precursor ingot and after amorphization by melt spinning was observed to vary between 2% and 3%.

Summary: Ultra-Rapid Annealing (URA) is an effective method for producing Fe-rich nanocrystalline soft magnetic materials. However, its scalability has been limited. In this study, a novel Continuous Ultra-Rapid Annealing (CURA) technique is introduced, which is suitable for industrial-scale production. Experimental results show that CURA can produce soft magnetic materials with comparable properties to URA and can be used for complex geometries, enhancing performance in commercial applications.

Summary: Based on Brown's static equations of micromagnetics, the polarization of the scattered neutron beam of a bulk magnetic material is computed. The results provide closed-form expressions for the spin-polarized small-angle neutron scattering (SANS) cross sections and the ensuing polarization.

Summary: Nanocrystalline alloy samples with different mean grain sizes were prepared to study the effect of grain size on core losses. The core loss was measured and separated into hysteresis loss, classical eddy current loss, and excess loss. The hysteresis loss showed a dependency on grain size, while the excess loss exhibited a power dependence on frequency. The influence of grain size on total core loss varied with frequency.

Summary: Abnormal magneto-transport properties, including thickness-dependent magnetoresistance and Hall effect, are found in CST nanoflakes. The sign reversal of magnetoresistance ratio and the transformation of Hall effect behavior are attributed to the variation of spin correlation with thickness in CST. These findings provide a basis for spintronics device design and offer new insights into the relationship between sample thickness, transport properties, and spin correlation in vdW ferromagnets.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
