用磁测量、Ｘ射线衍射及热磁分析等测试技术和双相无规磁各向异性模型，研究了Ｆｅ７３．５Ｃｕ１．０Ｎｂ３．０Ｓｉ１３．５Ｂ９纳米软磁合金的磁性与有效磁各向异性及铁磁相饱和磁化强度的关系，发现在不同晶化退火温度Ｔａ下，当有效磁各向异性〈Ｋ〉达最低值、合金中非晶相的饱和磁化强度σＡＳ与αＦｅ－Ｓｉ纳米晶的σαＳ之比σＡＳ／σαＡ＝０．５５时，合金的软磁性能最高。
The magnetic and effective magnetic anisotropy of Fe73.5Cu1.0Nb3.0Si13.5B9 nano-soft magnetic alloy and the properties of iron The results show that when the effective magnetic anisotropy (K) reaches the lowest value, the saturation magnetization σAS of the amorphous phase in the alloy and the σαS of the αFe-Si nanocrystal at different crystallization annealing temperature Ta Compared with σAS / σαA = 0.55, the alloy has the highest soft magnetic properties.
