Abstract
In this study, FeNi-based amorphous alloys having crystallization temperature (Tx) close to FeNi order-disorder
transition temperature were developed. Through an extended annealing process at around the crystallization
temperature, an ordered phase, L10-FeNi, was formed. Structural characterizations of annealed ribbons
confirmed the formation of L10-FeNi phase through observation of a weak superlattice peak. Measured coercivity
(Hc) also indicated formation of the ordered L10-FeNi phase, which increased up to 744 Oe after the
annealing process.
