The interaction of Fe thin layers between MgO(100)-MgO and MgO(100)-Ag surfaces

The atomic interaction and magnetic properties of ultrathin Fe films grown on cleaved and polished MgO(100) surfaces were studied by conversion electron Mössbauer spectroscopy (CEMS) in broad temperature range. Fe with different layer thickness was deposited on MgO substrates. The layers were formed on polished and cleaved substrate surfaces at RT. The analysis of the spectra showed no Fe-O$^{2-}$ interaction in MgO/Fe interface. Iron layers showed different magnetic anisotropy depending on their thickness.

Ironsilicide formation by high temperature codeposition of Fe-2Si with different thicknesses on Si (111)

Fe and 2Si were co-deposited on Si (111) surface at 853 K. The formation of silicides was investigated by Mossbauer spectroscopy and electron microscopy. Depending on the thickness of the deposited films different phases were formed. At low thickness, stable $ε$-FeSi (B20) and metastable [CsCl]-Fe$_{1-x}$Si (B2) phases were observed. In the latter case, because of the presence of Fe vacancies in the lattice the local symmetry around the iron components was lower than cubic. At larger (12 nm) deposited thickness, stable $β$-FeSi$_2$ has been formed.
