The influence of Co addition on structural and magnetic properties of nanocrystalline (Fe100-xCox)73.5Si 13.5B9Nb3Cu1 (x = 10, 20, 30, 40, 50, 80) alloys has been studied using DSC, Mössbauer spectrometry, XRD and magnetic measurements. Results show that a Fe70Co30-like nano-phase containing a small amount of Si precipitate in Co-rich alloys (x ≥30 ), whereas other alloys exhibits the characteristics of DO 3FeSi nanoparticles containing a small amount of Co. Exception is found for equi-atomic alloy (x=50), which decomposes into two phases having different Si content. This drastic change of microstructure for x ≥30 directly affects the magnetic properties because of the precipitation of a harder magnetic phase compared with alloys having a low Co content.
