✦ Synopsis

Electronic structures of NdxFel00_ x (11 ~< x ~< 60) and (NdxFeloo_x)s4B16 (0 ~< X ~< 60) alloy glasses produced by melt spinning are studied by X-ray photoemission spectroscopy. Core level Nd 3d and Fe 2p and valence band spectra of these alloys are measured and compared with those of pure metals. The valence band spectra, which mainly project the partial density of states of Fe 3d bands of the alloys, manifest quite different features between the two systems. This difference is attributable to different local structures, and hence different bonding characteristics, of Fe atoms between the two systems. The valence band spectra are also influenced by hydrogenation. This somewhat enhances the Fe 3d peak relative to the Nd 4f core level peak. Its effect on bonding of Fe atoms is discussed.

The local structure ofNd Fe-B amorphous alloys was studied by Nd L 3 XAFS. The amorphous alloys were prepared by melt-spinning, mechanical grinding and mechanical alloying techniques. It was concluded that the local structures around the Nd atoms of the amorphous alloys strongly depend on the differ
