Abstract:Based on the nearly-free-electron model, a method to estimate the total effective conducting electron numbers Zth 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 R0exp and electron specific heat coefficient γexp in Ni-based amorphous alloys, it is found that they are in good agreement with each other.
Key words: amorphous Ni-based alloy effective conducting electron number nearly-free-electron model
