A set of La1–xYxMn2Si2(57Fe) samples withx=0, 0.1, 0.15, 0.2, 0.25, 0.3, 0.5 and 1.0 have been prepared with the tetragonal ThCr2Si2 structure.57Fe Mössbauer spectra have been collected at 4.2 K for all samples. The spectra can be well fitted by two sextets, the predominant one (90% of the spectral area) being associated with57Fe atoms in the Mn 4d site, with the remainder located in the Si 4e site. The analysis shows that there are distinct changes in the hyperfine interaction parameters for samples above and below the critical concentrationx

0.15, at which a transition from ferromagnetism to antiferromagnetism occurs. This transition is a result of a change in the exchange interactions linked with changes in the interatomic distances, due to the smaller atomic volume of Y compared to that of La.On leave from Applied Acoustics Institute, Shaanxi Teachers University, Xian, PR China. 相似文献

Unsaturated isobutylamide synthons are employed to make seven natural amides. The ()-selectivity of the Wittig reaction towards the newly formed olefinic bond in the seven examples is estimated by 13 Cmr. 相似文献

Co-Se thin films prepared by magnetron sputtering have shown significant activity for the oxygen reduction reaction. One sample, after sectioning by ultramicrotomy, was studied by high-resolution scanning transmission electron microscopy (HRSTEM) and scanning Auger microscopy (SAM), and X-ray diffraction (XRD) was used for characterizing further samples. These thin films were shown to have Co-Se nanocrystals embedded into Se-rich matrices. The TEM and XRD results were consistent with the nanocrystallites being non-stoichiometric with structures related to those of monoclinic Co1−xSe (x=0.125-0.25). 相似文献
