| Abstract: | Polarized neutron diffuse scattering measurements have been made of two single crystal specimens of the ordered intermetallic compounds Fe2.45Mno.55Si (at room temperature and Fe2MnSi (above and below the re-ordering temperature). The difference between spin-flip and non-spin-flip scattering cross-sections for the (111) position gave a negative diffuse peak around a positive Bragg peak, being more pronounced for the Fe2.45Mno.55Si crystal. This is consistent with a loss of moment on the B(Fe/Mn) site with addition of Mn. Preliminary model fitting has suggested that Mn atoms cluster on their preferred B-site. |
