Abstract

We performed soft X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD) measurements at Fe L2,3-edges and Ce M4,5-edges on Ce2Fe14B at 300 K. The valence and total atomic moment of Ce in Ce2Fe14B were determined to be ∼+3.12 and ∼0.100 μ B, respectively, which mainly stem from a large portion of the well-localized 4f 1 configurations. Besides, the individual orbital and spin moments of Ce in Ce2Fe14B as well as those of Fe were determined for the first time with consideration of the magnetic dipole term.
