Fe-based amorphous alloys in Fe- (Al,Ga)-(P,B,C,Si) system were found to exhibit a wide supercooled liquid region exceeding 50 K before crystallization. The high stability of the supercooled liquid enabled the production of cylindrical bulk amorphous alloys with diameters up to 2 mm by copper mold casting. The Fe-based bulk amorphous alloys exhibit ferromagnetism with the Curie temperature of about 600 K The saturation magnetization (Bs), coercivity (Hc) and permeability (μe) at 1 kHz in as-quenched state are 1.07 T, 12.7 A/m and 3600, respectively, for Fe73Al5Ga2P11C5B 4 and 1.14 T, 0.5 A/m and 3200, respectively for Fe72Al5Ga2P10C6B 4Si1. Besides, the use of the Fe-based amorphous alloys enabled the production of thick amorphous ribbons above 100 μm in thickness and the thick samples also exhibit good soft magnetic properties. The success of synthesizing the bulk Fe-based amorphous alloys with good soft magnetic properties is promising for future development as a new type of soft magnetic materials.
