摘　　要：按照Ａｌｂｅｎ非晶无规磁各向异性的处理方法，考虑纳米软磁合金的双相组织结构的特点，提出了双相无规磁各向异性模型，得到了纳米软磁合金的有效磁各向异性与显微结构参数及铁磁相磁特性参数间的关系，探讨了磁性与有效磁各向异性的关系．用Ｆｅ７３５Ｃｕ１０Ｎｂ３０Ｓｉ１３５Ｂ９０纳米软磁合金的Ｘ射线衍射结构分析及磁测量结果进行了分析及验证。Following the random magnetic anisotropy model proposed by Alben for amorphous ferromagnets and taking into consideration the two phase microstructure of nanostructured soft magnetic alloys, we propose a two phase random magnetic anisotropy model for nanostructured soft magnetic alloys.We obtain the relationship of the effective magnetic anisotropy density with the microstructure parameters and magnetic parameters of ferromagnetic phases in the alloy,and also the dependence of the magnetic propertics on the effective magnetic anisotropy density.The experimental results of X ray diffraction and magnetic measurements of Fe 73 5 Cu 1 0 Nb 3 0 Si 13 5 B 9 0 nanostructured soft magnetic alloys give favourable support to the above theoretical research.
