MÖSSBAUER SPECTROMETRY IN FeMCuB-TYPE NANOCRYSTALLINE ALLOYS: I. THE CASE OF M = Mo

Marcel Miglierini

   57Fe Mossbauer spectrometry is used to elucidate the nature of hyperfine interactions in amorphous and nanocrystalline forms of Fe80M7Cu1B12 (M=Mo) alloys. Completely paramagnetic as-quenched amorphous alloy shows a distribution of quadrupole splittings. After partial crystallization, a wide range of hyperfine interactions is observed. They are evaluated using two proposed approaches to the spectrum itting. The obtained hyperfine field distributions are decomposed into Gaussian components which together with three-dimensional mappings of the distributions provide quantitative and qualitative basis for a design of topography of hyperfine interactions. Extension of the present work towards M=Nb, and Ti alloys is reported in part II, the following paper.

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