Ferromagnetic Characteristics of Bulk Fe₆₃Co₇Nb₄Zr₆B₁₉Si₁ Metallic Glass

Article Preview

Abstract:

By copper mold casting, a bulk Fe₆₃Co₇Nb₄Zr₆B₁₉Si₁ metallic glass was synthesized in the diameter of 2mm. The Fe-based amorphous alloy exhibits soft ferromagnetic characteristics with a saturation magnetization of 77Am²/kg and a saturated magnetostriction of 25.4×10^-6. The saturation magnetization is reduced while the coercive force is slightly lowered by annealing treatment below the crystallization temperature. The devitrification gives rise to a remarkable enhancement both in saturation magnetization and coercive force.
