“…On the other hand, even with the existing sapphire crystals, improving the monochromator properties can be achieved by improving the efficiency of the transversal focusing and implementing this focusing above 30 keV. Besides the Mö ssbauer isotopes studied in this work, one can apply the monochromator to carry out nuclear inelastic scattering measurements with 161 Dy at 25.66 keV (Chumakov et al, 2001), 201 Hg at 26.27 keV (Ishikawa et al, 2005a), 189 Os at 36.18 keV and 129 Xe at 39.58 keV.…”

“…Although from the 57Fe spectra only the partial phonon density of states results, i.e. the DOS, composed ofthe only vibrational states, in which the resonant nuclei are involved, a robust change may occur in the partial DOS at magnetic transitions, as was shown by Chumakov et al [9] in the case of the 173K-transition in [Fe(bpp)2] [BF4h.…”

Phonon anomalies near the critical temperature are studied in a number of itinerant ferromagnets, including (Fe,Co )-based perovskite-related oxides, the 57Fe-doped ruthenates and the manganite LaO.7SrO.3Mn03. The partial 57Fe phonon densities of states (DOS) in these oxides were derived from the resonant nuclear inelastic scattering spectra. The spectra were measured with energy resolution of 2.5meV by detecting the 6.3 keY Fe Ka X-rays following after Mossbauer effect on 57Fe transition excited by monochromatized 14.41 keY synchrotron radiation. The changes in the 57Fe phonon DOS g(E) are observed at cooling across Te. In the perovskites Sr2FeCo06_3 and SrBaFeCo06_3, the lowest energy peak near 15 meV develops below Te. We attribute this change to the narrowing of the phonon bands at the onset of the transport coherence. The non-metallic brownmillerite SrCaFeCo05 exhibits a peak in the much lower energy region of g (E). In the g(E)/g curve, a strong low-energy deviation from Debye behavior (g(E)/g= const) appears at 7 meV. This peak enlarges dramatically the vibrational amplitudes for brownmillerites relative to perovskites.

“…This is an important aspect for nuclear inelastic spectrocopy involving Fe that does exhibit a significant incoherent cross section for inelastic neutron scattering. The method has been applied to determine vibrational properties of other elements like Sn, [32][33][34][35] Dy, 36 or Eu. 37 The iron islands were prepared by thermal evaporation of 57 Fe (95% enriched) from a crucible under ultra-high vacuum conditions on a clean vicinal surface of a W(110) single crystal.…”

Nuclear resonant scattering of synchrotron radiation is applied to investigate the magnetic structure and the lattice dynamics of nanoscale systems. The outstanding brilliance of modern synchrotron radiation sources allows for sensitivities to smallest amounts of material. Due to the isotopic sensitivity of the scattering process, ultrathin probe layers of Mössbauer isotopes can be used to map out the magnetic and vibrational structure of thin films with sub-nm spatial resolution. Elastic nuclear resonant scattering is applied to determine the magnetic spin structure of an exchange-coupled bilayer system. Inelastic nuclear resonant scattering was used to determine the vibrational density of states in Fe islands on the W(110) surface.
