Hard magnetic Nd60Fe30Si10 amorphous ribbons with large thicknesses up to 107 μm were prepared by melt spinning. The hard magnetic properties of this alloy increase with increasing ribbon thickness to 107 μm, and the largest values of remanence, coercivity (iHc) and maximum energy product (BH)max are 0.15 T, 412kA/m and 3.8kJ/m3, respectively. The main feature of this amorphous alloy is that the hard magnetic properties with high iHc are obtained in the melt-spun amorphous state without crystallinity. The combination of the large glass-forming ability and hard magnetic properties is important for the future development of hard magnetic bulk amorphous alloys.
