“…The Lα 1 -detected X-ray absorption spectra recorded at the Sm L 3 -edge are dominated by a prominent absorption peak at ca. 6720 eV referred to as the white-line, 11 , 55 identified as the 2p → 6s and 2p → 5d electronic transitions, which are both dipole-allowed. Specifically, the L 3 -edge represents excitation from 2p 3/2 to both 5d 3/2 and 5d 5/2 states, and is preferred to the L 2 -edge which is limited to transitions from the 2p 1/2 to the 5d 3/2 state and therefore half as intense.…”

] has calculated the zero-field splitting parameter D of NiCl, and determined the crystal structure of NiC1, by using Zhao et al.'s model and fitting procedure [2]. Huang has demonstrated that Zhao et al.'s model cannot only interpret the zero-field splitting but also calculated the bond angle which is more exact than that determined by X-ray diffraction. However, Zheng [3] has critically pointed out that Zhao et al.'s model and fitting procedure are erroneous, and the results derived from the model and fitting procedure are unreliable. From the viewpoint of crystal structure, in this note we point out that the crystal structure of NiCl, determined by Huang is contrary to basic knowledge of crystal structure, so it is faulty. What we obtain is opposite to Huang's conclusion.By means In other words, the bond length and the bond angle determined by Huang are contrary to the geometric relation of the cystal structure, so the crystal structure of NiCI, determined by Huang is false.As is well-known, the EPR splitting parameter D is very sensitive to the bond angle 8, therefore a minute change of 8 will result in a bigger change of D [7]. Making use of the data of R and 8 determined by X-ray diffraction, the result D = -0.9 cm-' can be obtained with Huang's method. Comparing this value with the experimental D (= 1.35 cm-'), we can see the obvious difference. The signs of the two values are opposite and the relative error is 166%. Such a big error shows clearly that Zhao et al.'s fitting procedure is uneffective.With the same fitting method, Zhao and co-workers [8] have determined the crystal structure of MnF,. But the structural data determined by therm are contrary to the simple geometric relation of the crystal structure, so the crystal structure of MnF, determined by therm is false, as pointed out by Baur and Sharma [9].')

The Nd L3-edge XANES spectra of Nd-added FINEMET type soft magnetic alloys were characterized. Meltspun amorphous metallic alloys with compositions of Fe73.5Si13.5B9Cu0.5Nb3Nd0.5 and Fe73.5Si13.5B9Nb3Nd1 were heat-treated at 850 K for various durations up to 1 h in order to induce crystallization of nanocrystalline phases inside the alloys. The introduction of small amounts of Nd to the FINEMET-type alloys resulted in enhanced crystallization temperatures. The structural evolution of Nd over time was inferred based on changes of the Nd L3-edge x-ray absorption near-edge structure spectra. When coexisting with Cu atoms, Nd atoms clustered at the early stage of heat treatment and generally remained unaltered over time. In the absence of Cu atoms, however, the neighboring atoms of Nd changed over time. Magnetic properties of the heat-treated samples were discussed in connection with such local structural changes occurring at Nd sites in addition to the typical role of Cu atoms in crystallization behaviors.
