摘要

This paper reports x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD) studies at Fe L_(3,2) and Co L _(3,2)-edges to investigate the electronic structure of (Fe _(100 - x)Co_x)_(78)Si_9Nb_3B _9Cu_1 (0 < x < 95) alloys. The influence of controlled Co addition on electronic structural and magnetic properties of (Fe_(100 - x)Co_x)_(78)Si_9Nb _3B_9Cu_1 (x = 0, 20, 40, and 60) alloys has been investigated and it has been observed that Co exists as Co_2+/Co ~(3+), while Fe exists as a mixture of Fe0 (metallic) and Fe~(2+). 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 L3,2-edge it shows a diamagnetic behavior.
