Abstract
A multicomponent Fe73Al5Ga2P11C5B4 alloy has a wide supercooled liquid region before crystallization and ferromagnetism at room temperature. Structure and magnetic properties of melt-spun Fe73Al5Ga2P11C5B4 allo ys with the thickness from 15 to 230 mu m were investigated. The criti cal thickness for Fe based glassy alloy to maintain single amorphous p hase is about 135 mu m. Saturation magnetization (sigma(s)), coercive force (H-c) and effective permeability (mu(c)) at 1 kHz indicate const ant value, 1.8 x 10(-4) Wbm kg(-1), 3 A m(-1) and 8000 respectively, w ith the sample thickness of 135 mu m. The magnetic properties of Fe ba sed 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 a lloy will be amorphous bulk material which has good soft magnetic prop erties. (C) 1997 Elsevier Science S.A.
