Description
The effect of Ni substitution on hyperfine fields of the iron atoms in the Fe4N is investigated. Nanocrystalline nature of γ'-Fe4-xNixN materials was examined by XRD and SEM micrographs. The Moessbauer spectra were modeled for hyperfine field distributions. Hyperfine fields for the iron atoms, (Fec) situated at the corner positions of the fcc lattice, increase dramatically with the Ni atom substitutions and the results are explained by electronic structure and the presence of local inhomogeneities.
