    119Sb emission Mossbauer spectra are measured for very dilute, quenched Au-Sb alloys. Two distinct satellite lines observed after quenching and subsequent annealings were assigned to vacancy-solute pairs and vacancy-solute ...
  • M Kawakami; H Enokiya; T Okamoto (1985-07-01)
    NMR measurements of 197Au in Fe and FCC Co alloys with 0.1 at.% Au have been made using powdered specimens in zero external magnetic field at 1.7K. Electric quadrupole splitting has been found in the spectra. The spacing ...
  • K D Sen (1984-02-01)
    New results for the uncoupled Hartree-Fock estimates of the 3d contribution to the ionic antishielding factor, gamma infinity 3d, are reported for Sc-Ni in the electronic configuration 3dn4s1. It is found that gamma infinity ...
  • F Vargand; D Fargues; E Belin; C Bonnelle (1981-09-01)
    2p32/-3d emission and absorption spectra of nickel in small metallic crystalline particles are studied. The samples are thin nickel films prepared by vacuum deposition using the Al-Ni-Al sandwich method. Their structure ...
  • R M Nieminen; M Puska (1980-05-01)
    Self-consistent spin density functional calculations have been carried out for 3d transition metal impurities in aluminium. The width of the virtual level decreases as it moves away from the Fermi energy with increasing ...
  • E Belin; L Schlapbach; M Gupta (1983-10-01)
    An SXS experimental determination of valence density of states has been performed for Pd in PdHx (x approximately 0.6). From their results, the authors ascertain that in PdHx a structure at about 7.4 eV from the maximum ...
  • G Strasser; F U Hillebrecht; F P Netzer (1983-10-01)
    Core electron energy loss spectra (CEELS) of 4d to 4f excitations are presented for Ce intermetallic compounds. The spectral fine structures of 4d94fn+1 final states show features which can be correlated to the f-count as ...
  • M M Islam; D J Newman (1975-05-01)
    An apw calculation has been made giving the 4f band energies in h.c.p. Tm metal for four high symmetry values of k. Crystal field parameters are determined and compared with experimental results for dilute systems. It is ...
  • J B Dunlop; J M Williams; G Longworth (1978-10-01)
    Previous studies of dilute ZnFe alloys have indicated that, although the iron atom does not possess a well defined localised magnetic moment, it is on the verge of magnetism. In this work alloy samples containing up to 0.4 ...
  • S Nasu; U Gonser; P H Shingu; Y Marakami (1974-02-01)
    57Fe Mossbauer spectra of highly supersaturated Al-Fe alloys containing 0.5, 1, 3 and 5 at % Fe were obtained. The spectra were interpreted as a superposition of a single line due to isolated Fe atoms and broad quadrupole ...
  • S K Kulshreshtha; P Raj (1982-02-01)
    57Fe Mossbauer investigations have been reanalyzed to estimate the components of the anisotropic hyperfine coupling tensor Aapproximately ; from the complex spectra of FeSn at temperatures below TN, and those of Mn-substituted ...
  • S K Arif; D St P Bundbury; G J Bowden; R K Day (1975-05-01)
    See also ibid., vol.5, no.5, p.1037 (1975). The methods described in the previous paper are used to analyse the complicated 57fe mossbauer spectra of the (re)fe3 intermetallic compounds, where re=gd, tb, dy, ho, er and y. ...
  • D I C Pearson; J M Williams (1979-09-01)
    The authors study the HCP ( epsilon phase) alloys of Fe with Ru and Os, containing 15 and 30 at.% of the alloying element, using 57Fe Mossbauer absorption spectroscopy. The existence of antiferromagnetism in the Fe-Ru and ...
  • P Bernier; H Alloul (1976-06-01)
    An experimental study is presented of the host 63Cu nuclear relaxation induced by paramagnetic impurities (Mn,Cr,Fe), in low external field (0G<H<1000 G) and at low temperature (1.2K<T<20K). It is shown that the diffusion-limited ...
  • H Alloul; P Bernier (1974-06-01)
    The 63Cu nuclear spin lattice relaxation rate (T1)-1 in Cu-Mn and Cu-Cr dilute alloys, measured between 0.32 and 20K, are interpreted in the light of recent spin diffusion studies done by the authors (1972) in Cu-Mn alloys. ...
  • P Bernier; H Alloul (1973-04-01)
    The recovery of the 63Cu nuclear magnetization in dilute CuMn alloys has been studied over wide ranges of field and temperature (1<H<51 kG, 0.32<T<77 K). Depending on the experimental conditions exp-(t/T1) or exp-(t/ tau ...
  • M Mali; J Roos; M Sonderegger; D Brinkmann; P Heitjans (1988-03-01)
    The authors report measurements of the 6Li and 7Li diffusion coefficient DNMR in both natural Li and enriched 6Li by the NMR pulsed magnetic field gradient techniques. Between 350 K and the melting point (454 K) DNMR obeys ...

    Mossbauer spectra with 155Gd were taken of a Gd2Fe14B single-crystal absorber. These spectra, which ave a more pronounced structure than those of powder absorber, lead to considerably improved precision in the hyperfine ...
