Enhanced mechanical and wave‐absorption properties of SiC–Si3N4–FeSi porous ceramics by introducing Al

Journal of The American Ceramic Society
SiC‐based porous ceramic wave‐absorbing materials have attracted much attention due to their excellent properties such as low density, high‐temperature resistance, and oxidation resistance. In this work, the impedance matching of SiC ceramics is improved

Magnetic Phase Transition in the Csci Fesi Spacer in Fe/FeSi Multilayers

MRS Proceedings, 1995
ABSTRACTWe report the formation of the CsCI FeSi phase in Fe/FeSi multilayers with constant Fe thickness and varying FeSi layer thickness. The crystallographic and magnetic properties of this metastable FeSi phase are determined in thick (62 nm) epitaxial silicide layers with ion channeling, X-ray diffraction and Mossbauer spectroscopy measurements ...

Thermoelastic Properties of B2‐Type FeSi Under Deep Earth Conditions: Implications for the Compositions of the Ultralow‐Velocity Zones and the Inner Core

Journal of Geophysical Research: Solid Earth
The CsCl‐type (B2) phase of FeSi (B2‐FeSi) has been proposed as a candidate phase in the ultralow‐velocity zones (ULVZs) at the base of the lower mantle and in the Earth's inner core.

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 ...

Static compression of $epsilon$-FeSi

Journal of the Korean Physical Society, 2010
X-ray diffraction patterns of -FeSi have been measured at pressures up to ∼53 GPa with good signal-to-noise ratio and high resolution by using synchrotron radiation. In order to refine the crystal structure, a Rietveld analysis has been performed. The structure of -FeSi is cubic with space group P213 and a = 4.4781 ± 0.0026 A.

Brillouin scattering in FeSi/X/FeSi double-layer films, X=ZnO and SiO2

Journal of Applied Physics, 1990
Thermally-excited spin waves in double-layer films of FeSi/X/FeSi (where X=ZnO and SiO2) have been studied by Brillouin scattering. The thickness of the FeSi (2.6 wt. % of Si) layers is fixed at 1100±30 Å. Scattering from the Damon-Eshbach-type surface wave and the standing spin waves has been observed.

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.

Paramagnetic Excited State of FeSi

Physical Review, 1967
The anomalous behavior of the temperature dependence of the susceptibility and specific heat of the intermetallic compound FeSi is reexamined from both an experimental and a theoretical point of view. It is shown that a consistent set of experimental data is obtained below a temperature of about 700\ifmmode^\circ\else\textdegree\fi{}K.

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 ...

Low temperature magnetostriction in FeSi

Journal of Magnetism and Magnetic Materials, 1986
Abstract The longitudinal and transverse components of magnetostriction of the cubic B-20 type compound FeSi have been measured in the temperature range 1 to 29 K. The transverse magnetostriction is found to be positive and highly anisotropic; the longitudinal magnetostriction is negative and much smaller.
