Study of hyperfine interactions in the intermetallic compound CePd2Si2 using PAC technique with 111Cing .In→ .Cd probe nuclei. Samples of CePd.Si. were prepared by melting constituent elements in an arc furnace under pure argon atmosphere. Carrier-free .In nuclei were introduced into the samples by thermal diffusion at 800°C in vacuum during 12 h. The measurements were performed in the temperature

M?ssbauer characterization of Fe-doped ZnO prepared by mechanical millings investigated. ZnO powder with 10 at. % admixture of Fe, FeO or Fe.O., were milled during 1, 4 or 16 h and characterized by X-ray diffraction and M?ssbauer spectroscopy. Different phases were obtained according to the initial conditions (precursor used, atmosphere, etc.) and phase’s formation entha

Temperature dependence of the hyperfine fields in NiFe2O4 and CuFe2O4 oxides(79≤.≤900 K) are well fitted by two sextets associated with .Fe nuclei at tetrahedral (A) and octahedral (B) sites. The Curie point Tc was deduced by zero velocity M?ssbauer technique to be 873±3 K. The hyperfine fields are observed to vary with temperature according to the equation . where .=1 (bas

Investigation of the different nature of magnetic hyperfine fields of Ce probes in Gd and Co matriced from first-principles electronic structure calculations. It was found that the origin of the MHF for these two situations is completely different even though the total MHF presents similar values on both the cases. For Ce diluted in Gd, the Ce . shell is localized and the orbital MHF dominates. On
