非晶合金Fe_(76.5-x)Cu_(1.0)Nb_xSi_(13.5)B_(9.0)的穆斯堡尔研究

Mossbauer Study of Fe_(76.5-x)Cu_(1.0)Nb_xSi_(13.5)B_(9.0) Amorphous Alloys

非晶合金Fe_(76.5)-xCu_(1.0)NbxSi_(13.5)B_(9.0)(x-1,3,5和7)的穆斯堡尔研究表明,Nb元素对非品合金的磁有序温度Tc和超精细相互作用有很大的影响。Nb元素使非晶体Fe-Fe间的平均磁相互作用减弱,是造成非晶合金结构不均匀的重要因素。

Mossbauer studies of Fe76.5-xCu1.0NbxSi13.5B9.0(x = 1,3,5 and 7) amorphous alloy have shown that the element of niobium has dramatic influence on magnetic ordering temperature Tc and hyperfine interaction structure for amorphous alloy. Niobium reduces averge magnetic interaction between Fe - Fe atome in amorphous matrix, which is an important factor leading to inhomogeneity in structure of the amorphous alloy.
