中文摘要	Co- and Fe-based amorphous alloys can be used as core and sensor materials for inductive applications. However, de-spite the requirement for a high cooling rate of almost 106K/s for the formation of an amorphous phase,1 the glass-forming ability (GFA) is poor for the ferromagnetic amorphous alloys, which limits the shape and dimension to thin film, sheet, pow-der and wire, and, therefore, restricts their application fields. For example, the large number of air gaps left between thin ribbons would cause a decrease in the core packing density and decrease the efficiency of the transformer. So it is impor-tant to improve the GFA of ferromagnetic amorphous alloys to eliminate the limitation of the sample shape and dimension. Since the first synthesis of Fe-based bulk glassy alloy (BGA) in 1995,2 a number of ferromagnetic BGAs have been devel-oped for the purpose of applications as functional and struc-tural materials.3–12 Among them, Co-based BGAs are drawing increasing attention due to their excellent soft-magnetic prop-erties.6,11 However, few studies about ring-shaped bulk sam-ples with good soft magnetic properties have been reported in Co-based glassy alloys. Recently, CoFe(Ni)BSiNb BGA with high GFA was synthesized by copper mold casting, 13 which made it possible to produce ring-shaped bulk samples. In order to suppress the intermediate working process and increasing the efficiency of the transformer for a core shape sample, Co-based (Co0.6Fe0.3 Ni0.1 )68(B0.811 Si0.189 )27Nb5 ring-shaped bulk samples with an outer diameter of 10 mm, an inner diameter of 6 mm, and a thickness of 1 mm (A10 mm A6mm t1 mm) were successfully synthesized by copper mold casting. This paper is intended to present the soft magnetic properties of the ring-shaped (Co0.6Fe0.3Ni0.1)68 (B0.811 Si0.189)27Nb5 BGA samples prepared by copper mold casting.
