Abstract

X-ray magnetic circular dichroism (XMCD) of Pd_97.1Fe _2.9 fine particle samples is studied at the Pd L_2,3 edges. The magnetic moment of a Pd atom, which is estimated using the magneto-optical sum rule, is ∼0.06μ_B/atom independent of particle size, while the total magnetization of the particle samples decreases monotonically with decreasing particle size. We attribute the size dependent magnetization to a reduction in the Fe magnetic moment at the surface region with decreasing particle size. Analysis of the XMCD data is reported in detail.
