Abstract:
|
The spin reorientation transition in DyFe11Mo around the spin reorientation temperature (220K) is
investigated by M??ssbauer spectrometry. The temperature dependence of the hyperfine parameters for each
Fe site reveals an obvious discontinuity of the hyperfine field. The magnitude of the discontinuity is more
important for the 8f site than for the 8i and 8j sites, indicating that the most prominent contribution to the
overall anisotropy in the Fe sublattice should be from the Fe ion at the 8f site. This is attributed to the
3d(Fe(8f))-3d(Mo(8i)) hybridization, which may play a quite important role in R(Fe,Mo)12 compounds. ??
