Hopping conductivity in FeSi [PDF]
Solid State Communications, 1995 Abstract We measured the ac conductivity of polycrystalline FeSi at temperatures 80 mK ≤ T ≤ 450 K and frequencies 20 Hz ≤ v ≤ 1 GHz. At temperatures T 25 K and deviations of the temperature dependence of the dc resistivity from a thermally activated behavior which occur below 90 K are not due to Anderson localization but probably to Kondo-like ...

Physical Review B, 1995
We show that a simple model involving two narrow (\ensuremath{\simeq}500 K) peaks in the density of states (DOS) at the edges of a narrow (\ensuremath{\simeq}1000 K) gap can account for the observed anomalies in the magnetic susceptibility, specific heat, thermal expansion, and elastic response of FeSi.

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 ...
