Abstract

Thermal and magnetic properties of a recently developed metallic glass of four different compositions [{Co(1−x)Fe(x)}(0.75)B(0.2)Si(0.05)]96Cr4 were evaluated, where x = 0, 0.1, 0.2, and 0.3. Coercivity decreased and saturation magnetization increased with the increase in iron content. All alloys showed a high Curie temperature. The trend in thermal stability and magnetic properties was explained by atomic interactions between the constituent elements and sd hybridization between the ferromagnetic metal and the metalloid atoms.
