We report a ductile Fe-Mo-P-C-B bulk metallic glass (BMG) with good soft-magnetic properties. The Fe-Mo-P-C-B BMG with high Poisson';s ratio of 0.325 and low glass transition temperature of 708 K exhibits plastic strain up to 5.5% before final failure and high fracture strength of 3280 MPa in compression. The Fe-based BMG possesses high saturation magnetization of 1.1 T, low coercive force of 1.8 Am-1 and high permeability of 55300. The Fe-Mo-P-C-B BMG with this combination of noticeable ductility, high strength and good soft-magnetic properties previously not observed simultaneously in Fe-based glassy alloys has promising potential in functional and structural applications.
