We present small angle scattering measurements performed on Fe–Ag granular systems using polarised neutrons. Various samples with different iron concentration have been investigated and the analysis of the experimental data points out that samples morphology does not change remarkably with Fe content. Finally, the study of the polarised signal indicates the presence of Fe rich regions in the nanometer range of size having a negligible magnetisation.

Abstract
We present small angle scattering measurements performed on Fe–Ag granular systems using polarised neutrons. Various samples with different iron concentration have been investigated and the analysis of the experimental data points out that samples morphology does not change remarkably with Fe content. Finally, the study of the polarised signal indicates the presence of Fe rich regions in the nanometer range of size having a negligible magnetisation.File in questo prodotto:
