Correlations between the thermal properties and the electronegativity of soft magnetic Fe-based amorphous alloys

Abstract In this letter, we report clear correlations between the glass transition temperature T g , the crystallization temperature T x , the Curie temperature T C and the electronegativity based on statistically analyzing more than 200 kinds of soft magnetic Fe-based amorphous alloys. The underlying physical origin of these correlations is discussed. Based on these correlations, the influences of various alloying elements are classified. These results are helpful for designing new soft magnetic amorphous alloys with high thermal stability.
