Iron Diffusion Near Surface of Fe3Si is Fast- and Decays to Bulk Values within 3 nm
Nuclear resonant scattering (NRS) methods allow to determine diffusion coefficients and jump directions. The capability to measure the diffusion mechanism in ordered intermetallics on atomic scale by mean of NRS was shown in various experiments and in different geometries (transmission [1,2], Bragg , grazing incidence ). A combination of NRS and grazing incidence geometry can be used as a very sensitive tool to investigate thin films or near-surface-regions . Fe3Si with a D03 structure stable at high temperature and with a well known diffusion mechanism was chosen for this investigation.
