Fe-based soft magnetic metallic glasses have drawn substantial attention due to their high permeability, low coercivity (Hc) and low conductivity which contribute significantly to low core losses. However, inherent low saturation flux density (Bs) and/or low glass forming ability (GFA) of commercial Fe-based soft magnetic metallic glasses has hindered their further applications. In this work, Co was applied to partially replace Fe of Fe-Mo-P-C-B-Si system, then Fe-Co-Mo-P-C-B-Si alloy was obtained with GFA up to 1 mm and Bs better than 1.7 T, which is the highest Bs of Fe-based bulk metallic glasses reported so far. The Hc was also as low as 4.5 A/m. In addition, the 3050 MPa compression strength and better plasticity up to 1.2% also endow the alloys a better service performance. All these make them a promising candidate for commercial applications as magnetic functional and structural materials.
