    摘要:

    采用熔體單輥急冷法制備了非晶(Fe1-xCox)86Hf7B6Cu1 (x=0.4~0.6)合金，使用穆斯堡爾譜儀、透射電鏡（TEM）和振動(dòng)樣品磁強(qiáng)計(jì)(VSM)對(duì)其進(jìn)行了表征，穆斯堡爾譜和TEM結(jié)果表明所制樣品均為非晶態(tài)。然后借助于固體與分子經(jīng)驗(yàn)電子理論（EET理論），計(jì)算了非晶(Fe1-xCox)86Hf7B6Cu1合金的價(jià)電子結(jié)構(gòu)和磁矩，磁矩的理論計(jì)算值與實(shí)驗(yàn)測(cè)定值的誤差小于10%，滿足一級(jí)近似要求，實(shí)現(xiàn)了從價(jià)電子層次上計(jì)算非晶(Fe1-xCox)86Hf7B6Cu1合金的磁矩，這對(duì)于優(yōu)化非晶合金(Fe1-xCox)86Hf7B6Cu1的軟磁性能將具有理論指導(dǎo)意義。

    Abstract:

    Amorphous ribbons (Fe1-xCox)86Hf7B6Cu1 (x=0.4~0.6) were prepared using the single-roller melt-spinning technique. M?ssbauer Spectroscopy, transmission electron microscope (TEM) and vibrating sample magnetometer (VSM) were used to characterize microstructures and soft magnetic properties. The result confirms the fully amorphous state of the as-quenched alloy. The valence electron structures and the magnetic moment of the amorphous alloys were calculated using the method of Bond Length Difference (BLD) of the Empirical Electron Theory of solids and molecules (EET). The error of the computed value in theory and experimental value of the magnetic moment is less than 10%, which satisfies the demand of first approximation, indicating that magnetic moment calculation of amorphous alloy could be realized on the valence electron level.
