Title: Magnetic hyperfine field distributions in Fe{sub 73.5}Cu{sub 1}Nb{sub 3}Si{sub 13.5}B{sub 9}

Abstract

The ribbons of amorphous alloy of Fe{sub 73.5}Cu{sub 1}Nb{sub 3}Si{sub 13.5}B{sub 9} were isothermally annealed at the temperature 545 C in the range from 20 minutes up to 120 minutes. Three samples of different thicknesses of 33 {mu}m 27 {mu}m and 21 {mu}m were used. The obtained nanocrystals were studied by Moessbauer spectroscopy. The amount of remaining amorphous phase and average hyperfine field have been dependent on annealing time. Both these parameters have been decreased more rapidly for a thicker sample than for the thinner one. In P(H) distribution the authors observed a growing low field component and a vanishing high field component. The reason for such a different crystallization processes in various samples is the inhomogeneously distributed silicon along the ribbon thickness.
