Resonant Charge Relaxation as a Likely Source of the Enhanced Thermopower in FeSi

, 2014
The enhanced thermopower of the correlated semiconductor FeSi is found to be robust against the sign of the relevant charge carriers. At $T$\,$\approx$\,70 K, the position of both the high-temperature shoulder of the thermopower peak and the nonmagnetic ...

Realization of a Novel FeSiAlCuSn Multicomponent Alloy and Characterization of Intermetallic Phases Formed at Different Temperatures During Cooling

Metals
Ferrosilicon (FeSi) is a commercially important material with multiple uses in metallurgical processes. Recently, in an attempt to reduce the carbon impact of the FeSi production process, researchers have proposed using recycled Si recovered from ...

Correlation Effects on Optical Conductivity of FeSi

, 1999
Effects of electron correlation in FeSi are studied in terms of the two-band Hubbard model with the density of states obtained from the band calculation.

Lifshitz transition driven by spin fluctuations and spin-orbit renormalization in NaOsO$_3$

, 2016
In systems where electrons form both dispersive bands and small local spins, we show that changes of the spin configuration can tune the bands through a Lifshitz transition, resulting in a continuous metal-insulator transition associated with a ...

Absence of localized-spin magnetism in the narrow-gap semiconductor FeSb2

, 2011
We report inelastic neutron scattering measurements aimed at investigating the origin of the temperature-induced paramagnetism in the narrow-gap semiconductor FeSb2. We find that inelastic response for energies up to 60 meV and at temperatures 4.2 K, 300

Ab Initio Study of the Conductivities of B2 FeSi Under Core‐Mantle Boundary Conditions

Geophysical Research Letters
While the ultra‐low velocity zones (ULVZs) may hold key information about deep Earth dynamics, their elusive state and origin remain enigmatic. Recent high‐pressure experiments suggest that ULVZs may originate from the B2 FeSi crystallization from the ...

Magnetoresistance of a Bulk Sample of FeSi

JETP Letters
The magnetoresistance, MR of a well-characterized bulk FeSi sample was studied. It is shown that after a chaotic behavior at temperatures below 6 K, the magnetoresistance of FeSi becomes regular functions of temperature and magnetic field. The observations suggest that the mean free path of carriers defines along with the unknown negative component the
