A multicomponent Fe73Al5Ga2P11C5B 4 alloy has a wide supercooled liquid region before crystallization and ferromagnetism at room temperature. Structure and magnetic properties of melt-spun Fe73Al5Ga2P11C5B 4 alloys with the thickness from 15 to 230 μm were investigated. The critical thickness for Fe based glassy alloy to maintain single amorphous phase is about 135 μm. Saturation magnetization (δs), coercive force (Hc) and effective permeability (μe) at 1 kHz indicate constant value, 1.8 × 10-4 Wbm kg-1, 3 A m-1 and 8000 respectively, with the sample thickness of 135 μm. The magnetic properties of Fe based glassy alloy annealed at 773 K for 600 s are compared with that of Fe78Si9B13 amorphous alloy. It is expected that the Fe based glassy alloy will be amorphous bulk material which has good soft magnetic properties.
