Conversion Electron Mossbauer Spectroscopy has been applied to the stu
dy of different novel expitaxially stabilized phases of the Fe-Si syst
em and also of Fe3Si films. The silicides have been grown by Molecular
Beam Epitaxy on Si(111). The Fe-57 Mossbauer parameters (isomer shift
delta, linewidth Gamma, quadrupole splitting Delta and magnetic held
H at the nucleus) are reported and discussed in terms of the local sur
rounding of the Fe nucleus.
