Epitaxial {beta}-FeSi{sub 2} thin films were grown on Si(111)7x7 clean surfaces by solid phase epitaxy in ultrahigh vacuum: iron deposition at low temperature and subsequent annealing. We found that a ferromagnetic interface layer of iron-rich silicides forms between a {beta}-FeSi{sub 2} surface layer and a Si(111) substrate spontaneously from transmission electron microscopy observations and magnetization measurements.
