FexPtySiz (x = 60-90, y = 10-70, z = 10-40) ribbons were prepared using a melt-spinning technique. Fully amorphous ribbons were obtained for alloys containing approximately 20-30 at%Si. Crystallization of the amorphous ribbons yielded composite structures of L1 0 FePt and Pt-Si intermetallic compounds for Fe45Pt 35Si20 and Fe47Pt28Si25. Fe45Pt35Si20 amorphous ribbons were annealed at 700K for 180min, producing a grain size of approximately 40 nm in diameter, and a maximum coercivity of 160 kA/m.
