The influence of controlled Co addition on electronic structural and magnetic properties of (Fe100-x,Co-x)(78)Si9Nb3B9Cu1 (x = 0, 20, 40, and 60) alloys has been investigated and it has been observed that Co exists as Co2+/Co3+, while Fe exists as a mixture of Fe (metallic) and Fe2+. The XMCD studies confirm these results and reveal that Co-ions are responsible for the room temperature ferromagnetism (RTFM) in the system, while at Fe L-3.2-edge it shows a diamagnetic behavior.
