MÖSSBAUER SPECTROMETRY IN FeMCuB-TYPE NANOCRYSTALLINE ALLOYS: II. THE CASE OF M = Nb, AND Ti

Marcel Miglierini

   Fe₈₀M₇Cu₁B₁₂ (M = Nb and Ti) alloys are studied by ⁵⁷Fe Mossbauer spectrometry in amorphous and nanocrystalline forms. The latter are obtained at different stages of crystallization through thermal treatment in protective atmosphere. Hyperfine interactions are examined by the help of an evaluation model which was introduced in part I, the previous paper. Three-dimensional mappings of the corresponding hyperfine field distributions enable us - after their decomposition into several Gaussian components - to sketch a structural model as well as a model of the topography of hyperfine interactions within FeMCuB-type nanocrystalline alloys.

Keywords: Mossbauer spectrometry, nanocrystalline alloys, hyperfine interactions, magnetic structure
