A family of iron-based, phosphor-containing bulk metallic glasses having excellent processability and toughness, methods for forming such alloys, and processes for manufacturing articles therefrom are provided. The inventive iron-based alloy is based on the observation that by very tightly controlling the composition of the metalloid moiety of the Fe-based, P-containing bulk metallic glass alloys it is possible to obtain highly processable alloys with surprisingly low shear modulus and high toughness. Further, by incorporating small fractions of silicon (Si) and cobalt (Co) into the Fe—Ni—Mo—P—C—B system, alloys of 3 and 4 mm have been synthesized with high saturation magnetization and low switching losses.
