Electron Energy Loss Spectroscopy: Probe of D-Band Occupancy in Amorphous Magnetic Alloys

摘要

L-edge EELS was used to study changes in d-band occupancy as a function of composition in amorphous binary magnetic alloys. It has been found that in the Fe/sub x/Ge/sub 1-x/ amorphous alloys there is no charge transfer from Ge to Fe observable by L-edge studies; rather, the data is consistent with a redistribution of d-band electrons causing increased spin pairing and a decrease in a magnetic moment for increased Ge content. In Fe/sub x/Si/sub 1-x/ alloys, however, charge transfer may be present. Differences in these systems are discussed. (ERA citation 12:004259)
