A Mössbauer Spectral Study of GdFe₁₁Ti and GdFe₁₁TiD
Iron-57 Mössbauer spectral measurements between 4.2 and 295 K have been carried out on GdFe11Ti and GdFe11TiD and analyzed with a model which considers both the uniaxial magnetic anisotropy and the distribution of titanium atoms in the near-neighbor environment of the three crystallographically distinct iron sites. The assignment and the temperature dependencies of the hyperfine fields and isomer shifts are in complete agreement with the Wigner-Seitz cell analysis of the three iron sites in GdFe11Ti and GdFe11TiD. The changes in hyperfine field and isomer shift with the number of titanium near neighbors of the three iron sites are in agreement with the values observed for related titanium-iron intermetallic compounds. The hyperfine parameters also agree with those observed in other RFe11Ti compounds and their hydrides. © 2003 Elsevier Science B.V. All rights reserved.
