Ferromagnetic Characteristics of Bulk Fe63Co7Nb4Zr6B19Si1 Metallic Glass

摘要：

　　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.
