“…Whereas, in the latter case, nanocrystalline Fe 3 B precipitated from liquid phase or amorphous precursor is generally undesirable, mainly because it is magnetically harder than Fe-based solid solution such as α-(Fe, Si) and α-(Fe, Co, Ni). Further, to improve the magnetic properties, alloying has been widely investigated and used [ 4 , 7 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. It was found that three effects can be achieved by alloying elements to affect the magnetic properties of these materials, as follows: (1) partitioning into phases and directly modifying their magnetic properties; (2) changing phase stability further to affect crystallization behaviors, and consequently influencing the size, distribution, content, and type of phases and (3) accelerating nucleation and/or suppressing the growth of phases by segregation.…”

“…Numerous experimental studies have been conducted. Results show that Cr [ 4 , 10 ], Co [ 11 ], Mn [ 12 ], V [ 13 ], W [ 14 ] and Mo [ 15 , 16 ] are closely related to the former two cases, whereas Cu [ 17 , 18 , 19 ], Nb [ 7 , 20 , 21 ] and Zr [ 20 ] more easily generate segregation due to their lower solubility. It has been reported that the partial substitution of Fe by Cr probably improves the stability of Fe 3 B [ 10 ], while Cr reduces its magnetic moments [ 23 , 24 , 26 ].…”

First-principles calculations were performed to investigate the site preference of alloying elements, and the effect of alloying elements on stability, electronic structure and magnetism of Ni3P-type Fe3B. The calculated energies suggested that all studied compounds are thermodynamically stable while it is relatively difficult to synthesize the (Fe2.875,Cu0.125)B, (Fe2.875,W0.125)B and (Fe2.875,Nb0.125)B. The (Fe2.875,W0.125)B is the most stable compound from the view of cohesive energy. Mn element prefers to occupy the Fe2 site, whereas the others are more likely to reside in the Fe1 site. It can be found from the electronic structures that the DOSs of both Fe3B and alloyed Fe3B are dominated by Fe-d states, and all the compounds mainly contain Fe-B covalent bond, Fe-Fe covalent bond and Fe-Fe metallic bond. Based on the magnetic moments (Ms) results, it can be known that the Fe3B, (Fe2.875,Mn0.125)B, (Fe2.875,Co0.125)B, (Fe2.875,Ni0.125)B and (Fe2.875,Cu0.125)B are ferromagnetic compounds, whereas the others are ferrimagnetic compounds. Only Mn and Co are able to enhance the magnetism of Fe3B. Moreover, Mn is the most favorable candidate for improving the magnetic properties of Fe3B among the alloying elements. These results can be used to guide the composition design and performance optimization of magnetic materials containing Fe3B with Ni3P-type structure.

Engineering Dielectric Loss of FeCo/Polyvinylpyrrolidone Core‐Shell Nanochains@Graphene Oxide Composites with Excellent Microwave Absorbing Properties

et al. 2020

View full text Add to dashboard Cite

FeCo alloy nanoparticles, as a kind of material with high saturation magnetization, have attracted wide attention in electromagnetic (EM) wave research. However, its application as a wave‐absorbing material is limited by its poor magnetic anisotropy and antioxidant properties. Herein, novel FeCo/Polyvinylpyrrolidone core‐shell nanochains@graphene oxide (GO) composites are successfully fabricated with superior microwave‐absorbing properties. The composites perform excellently in absorbing EM wave, with a strong reflection loss (RL) of −40.94 dB at 14.25 GHz, covering from 10.95 to 15.85 GHz (RL < −10 dB) with a matching thickness of 2.0 mm. The superior absorption properties are mainly attributed to the cooperation between amorphous magnetic FeCo nanoparticles and graphene, which contribute to the magnetic and dielectric loss, respectively. Moreover, the FeCo/PVP core‐shell morphology enhances the interfacial relaxation and surface chemical stability of the FeCo nanochains. Thus, this work provides a template for the new‐designed and facile‐synthesized EM wave‐absorbing material.
