摘要
用低频脉冲磁场处理非晶Fe78Si9B13合金,在低温下发生了纳米晶化,利用Mssbauer谱和LDJ9600震动样品磁强计进行了微结构和磁性分析。借助于固体与分子经验电子理论中的BLD方法,计算了非晶Fe78Si9B13合金磁致低温纳米晶化前后的价电子结构,并算出了磁矩,其理论计算值与实验测定值的误差小于7%,满足一级近似要求,说明从价电子层次上计算非晶合金的磁矩是可以实现的。
The amorphous Fe78Si9Bl3 alloy was treated by low frequency pulse magnetic field （LFPMF） and nanocrystallized at a low temperature. The microstructures and the magnetic properties of the untreated and treated alloys were analyzed by Mossbauer spectra and LDJ9600 vibrating sample magnetometer （VSM）. The valence electron structures and the magnetic moment of the unnanocrystallized and nanocrystallized amorphous alloys were calculated using the method of Bond Length Difference （BLD） of the Empirical Electron Theory （EET） of solids and molecules. The error of the computed value in theory and experimental value of the magnetic moment is less than 7%, which satisfies the demand of first approximation, indicating that it can be realized that magnetic moment of amorphous alloy is calculated on the valence electron level
