We study the diffusion of 57 Fe probe atoms in Fe/FeSi/Si/FeSi/Fe multilayers on Si(111) prepared by molecular beam epitaxy by means of 57 Fe conversion electron Mossbauer spectroscopy (CEMS). We demonstrate that the application of FeSi boundary layers successfully inhibits the diffusion of 57 Fe into the Si layer.

Temperature-induced magnetism in FeSi
Physical Review Letters, 1987We report neutron-scattering measurements with polarization analysis on a large single crystal of FeSi up to 650 K. A strongly q-dependent magnetic scattering is observed around (011) and the intensity follows the unusual shape of the static susceptibility. Surprisingly, the energy-integrated magnetic cross sections are almost q independent.

Band structure and electronic properties of FeSi and α-FeSi2
Journal of Applied Physics, 1994The results of self-consistent linear muffin-tin orbital calculations for the ordered end members of the FeSi1+x series, i.e., FeSi (x=0) with a CsCl structure and α-FeSi2 (x=1) with a tetragonal structure, predict semimetallic behavior for FeSi and metallic behavior and higher stability for α-FeSi2.

Abstract The inelastic neutron scattering from the unusual paramagnet FeSi has been measured at temperatures of up to 700 K in order to investigate the possible existence of a local magnetic moment at high temperatures. The estimated intensities of the central peaks around h ω = 0 and the nearly constant backgrounds ( h ω ≲ 16 meV ...

Metamagnetic transition of FeSi
Physica B: Condensed Matter, 2000Abstract A field-induced metamagnetic transition for FeSi is discussed by performing the fixed-spin-moment calculation on a self-consistent linear muffin-tin orbital method. The critical field of the metamagnetic transition is found to depend strongly on the lattice constant.

Abstract We have measured thermoelectric power, thermal conductivity and electric resistivity on FeSi samples, single crystal and polycrystals, with different qualities. Our data can be understood in terms of classic semiconductor physics. Good agreement is found with the results from recent band structure calculations.

Exchange coupling in Fe/FeSi/Si/FeSi/Fe structures with combined spacers
Transactions of the Magnetics Society of Japan, 2002Fe/FeSi/Si/FeSi/Fe epitaxial structures with combined spacers are prepared using co-evaporation. Combined spacers consist of Fe0.5Si0.5grown at elevated temperature and nominally pure Si. The thickness of each part of the combined spacers is varied from 0 to 20A.
