高类金属含量Ni基非晶合金总有效传导电子数的估算

CALCULATIONS OF TOTAL EFFECTIVE CONDUCTING ELECTRON NUMBERS IN Ni BASED AMORPHOUS ALLOYS WITH HIGH METALLOID CONTENTS

从近自由电子模型出发，考虑到类金属原子外壳层ｓ、ｐ电子向过渡金属原子未满ｄ壳层空位的迁移，提出了一种估算高类金属含量ＴＭＭ非晶合金总有效传导电子数的方法，通过与Ｎｉ基非晶合金Ｈａｌ系数和低温电子比热实验数据的比较。

Based on the nearly free electron model, a method to estimate the total effective conducting electron numbers Z th in Ni based amorphous alloys with high metalloid contents was given, by considering electrons moving from outer shell of metalloid atoms to unfilled d shell of transition metal atoms. As compared with the experimental data of Hall coefficient R exp 0 and electron specific heat coefficient γ exp in Ni based amorphous alloys, it is found that they are in good agreement with each other.
