MAGNETIC STRUCTURE OF NANOCRYSTALLINE ALLOYS

Marcel Miglierini - Jean Marc Greneche

   Magnetic structure of FeMCuB (M = Ti, Zr) nanocrystalline alloys which are strong candidates for technical applications is inspected by Mossbauer effect measurements. Two mutually independent distributions of hyperfine fields and one sextet of Lorentzian lines are employed to reproduce the amorphous residual phase, the interface zone, and the crystalline phase, respectively. The hyperfine field distributions obtained are analysed using their decomposition into Gaussian components. A model of topography of hyperfine interactions is proposed.

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