FeSi diffusion barriers in Fe/FeSi/Si/FeSi/Fe multilayers and oscillatory antiferromagnetic exchange coupling

Journal of Physics: Condensed Matter, 2008
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, 1987
We 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.

The influence of sputtering on FeSi

Journal of Materials Science, 1993
The effect of different (0.5, 2 and 4 keV) Ar+ energy ions on (a) the composition of an FeSi surface, (b) the oxidation of the FeSi surface after bombardment, and (c) the segregation of silicon after bombardment, has been monitored by Auger electron spectroscopy.

Magnetic properties regulation and loss contribution analysis for Fe-based amorphous powder cores doped with micron-sized FeSi powders

, 2020
The influences of annealing temperature and mass fraction of gas-atomized FeSi powders within a range of 0 ~ 16 wt% on the soft magnetic properties of Fe-based powder cores, prepared by cold compacting the mixture of the water-atomized FeSiBCCr amorphous

Metamagnetic transition of FeSi

Physica B: Condensed Matter, 2000
Abstract 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.

Simultaneous Enhancement of Low‐Frequency Microwave Absorption and Corrosion Resistance in FeSi Alloys via Magnetic‐Structural Heterojunction Engineering

Advanced Functional Materials
Soft magnetic alloys, featured with high permeability, hold significant potential in low‐frequency electromagnetic wave absorption. However, the limitations of narrow absorbing bandwidth and susceptibility to corrosion restrict their extensive ...

Biquadratic Coupling Contributions to the Magnetoresistive Curves in Fe/FeSi/Fe Sandwiches with Semiconductor like FeSi and Metallic bcc FeSi Spacers

Journal of the Physical Society of Japan, 1998
Magnetoresistance was investigated in Fe/FeSi/Fe sandwiches with metallic bcc- and semiconductor like FeSi spacers prepared by an ultrahigh-vacuum magnetron sputtering system, enhanced with inductively coupled RF plasma. In the easy axis direction, MR curves at 298 K have a dip around the zero magnetic field for both Fe/FeSi/Fe sandwiches with ...

Band structure and semiconducting properties of FeSi

Physical Review B, 1993
The results of linear augmented-plane-wave band calculations for cubic FeSi, carried out in the local-density approximation, predict a small (-0.11 eV) indirect semiconductor gap which agrees well with empirical estimates (-0.13 eV). The origin of this gap, which occurs within the Fe (3d) manifold, can be traced to a pseudogap that is present in the ...

Magnetic and electrical properties of FeSi/FeSi–ZrO2 multilayers prepared by EB-PVD

Journal of Magnetism and Magnetic Materials, 2003
Abstract FeSi/FeSi–ZrO2 and FeSi/ZrO2 multilayer materials were prepared by electron beam physical vapor deposition with the FeSi–ZrO2 layer thickness about 0.6 μm, and their magnetic and electrical properties were studied as a function of FeSi layer thickness.
