Abstract
We investigated the electronic structure of Fe x Pd1−x (x = 0.25, 0.5, and 0.75) alloys by measuring valence-band and core-level photoelectron spectra. The Fe 3d and Pd 4d partial spectral weights were determined by using the Cooper minimum phenomenon of the Pd 4d photoionization cross section. We found that the experimentally determined Fe partial spectral weight of Fe50Pd50 alloy differ much from the band calculation results, and we could not observe a spectral structure due to the Pd 4d states mixed with the Fe 3d majority states at the binding energy of 0.9 eV. We suggest that a plausible explanation for these discrepancies should be the spin-dependent lifetime of the Fe 3d states.
