Stability and magnetic properties of Fe-based amorphous alloys with supercooled liquid region

Abstract Ribbons and rods consisting of a single amorphous phase of Fe 77 Al 2.14 Ga 0.86 P 8.4 C 5 B 4 Si 2.6 have been prepared by melt spinning and centrifugal casting, respectively. A supercooled liquid region Δ T x =32 K was found. Differences in annealing behaviour of coercivity between ribbons and rods were observed. Magnetostriction and saturation polarization were 26.5×10 −6 and 1.30 T, respectively. Incubation time for crystallization as a function of temperature has been determined.
