The glass-forming ability, thermal stability and magnetic properties have been investigated for a Fe67Co9.5Nd3Dy0.5B25 glassy alloy with a large supercooled liquid region of 56 K prepared by the melt-spinning technique. The glassy phase is formed in the wide sheet thickness range from 19 to 203 \\micron. The glass transition temperature (Tg), crystallization temperature (Tx), supercooled liquid region (ΔTx=Tx−Tg) and heat of crystallization (ΔHc) remain almost unchanged in the thickness range below 203 \\micron. The Fe62Co9.5Nd3Dy0.5B25 glassy alloy annealed at 773 K for 600 s exhibit good soft magnetic properties of 1.41 T for saturation magnetization (Is), 2.6 A/m for coercive force (Hc), and 12000 for permeability (μe) at 1kHz in a thickness of 19 \\micron. The Is, Hc and Curie temperature (Tc) remain unchanged in the thickness range up to about 200 \\micron, but the μe at 1 kHz gradually decreases to 6700 for the thick sheet with a thickness of 203 \\micron.
