摘要采用无容器凝固法制备了Fe 76 Si 9 B10 P5非晶颗粒，并通过X射线衍射分析、透射电子显微镜和振动样品磁强计对其结构和磁性能进行了研究。退火诱导了α-Fe和Fe-B化合物的纳米晶化。形成的不同晶相的比例取决于退火温度。单颗粒的饱和磁化强度高于常规淬火工艺制备的样品，这归因于前者纳米晶晶粒的均匀性更高以及它们的α-Fe与Fe-B化合物的比例更高。图形摘要影响声明我们研究了通过无容器固化工艺获得的单个颗粒，以获得比通过常规工艺获得的样品更深入的磁特性。
ABSTRACT Amorphous Fe76Si9B10P5 particles were fabricated by a container-free solidification process and subsequent annealing, and their structural and magnetic properties were investigated by X-ray diffraction analysis, transmission electronic microscopy, and vibrating sample magnetometry. The annealing induced the nanocrystallisation of α-Fe and Fe-B compounds. The proportions of the different crystalline phases formed were dependent on the annealing temperature. The saturation magnetisation of the single particles was higher than that of the samples prepared by a conventional quenching process; this was attributable to the higher homogeneity of the nanocrystalline grains of the former as well as their higher α-Fe to Fe-B compound ratio. GRAPHICAL ABSTRACT IMPACT STATEMENT We have investigated single particles obtained by a container-free solidification process to gain deeper insight into their magnetic properties than is possible with samples obtained by conventional processes.
