Abstract

Fe₇₃Pt₅B₁₀Si₁₂ metallic glass was prepared to investigate the crystallization and ensuing changes in magnetic properties of the Fe-rich amorphous alloy. The Fe₇₃Pt ₅B₁₀Si₁₂ alloy crystallized at 470°C which was 50°C below the crystallization temperature of the Pt-free Fe ₇₈B₁₀Si₁₂. In addition, the Pt addition led to nucleation of Fe₃Pt compound in the final crystallization product of the amorphous alloy. Saturation magnetization of the Fe₇₃Pt ₅B₁₀Si₁₂ alloy increased substantially when annealed below the crystallization temperature, which led us believe that the amorphous alloy underwent a structural change. The Pt addition had far reaching effects on the amorphous structure of the Fe-rich glass as well as on the magnetic properties of the annealed alloy.
