Suppressed reflectivity due to spin-controlled localization in a magnetic semiconductor

open access: yes, 2005
The narrow gap semiconductor FeSi owes its strong paramagnetism to electron-correlation effects. Partial Co substitution for Fe produces a spin-polarized doped semiconductor.

The Effect of Vitamin D3 Supplementation on the Risk of Falls in a General Population—The Finnish Vitamin D Trial

open access: yesJournal of the American Geriatrics Society, EarlyView.
ABSTRACT Background The impact of vitamin D on fall incidence remains controversial. We studied the effect of 5 years of vitamin D3 supplementation on the risk of falls in a double‐blind, placebo‐controlled randomized trial with generally healthy, community‐dwelling men and women in Finland.

Observation of Double Weyl Phonons in Parity-Breaking FeSi. [PDF]

open access: yesPhysical Review Letters, 2018
Condensed matter systems have now become a fertile ground to discover emerging topological quasiparticles with symmetry protected modes. While many studies have focused on fermionic excitations, the same conceptual framework can also be applied to bosons

Is FeSi a Kondo insulator?

open access: yesPhysica B: Condensed Matter, 1997
FeSi exhibits a Curie-like susceptibility accompanied by a moderate electronic conductivity at high temperature. At low temperature the magnetic susceptibility goes to zero, and a small charge gap appears. We discuss phenomenological and theoretical aspects of the relationship between FeSi and various rare-earth correlated systems often referred to as ...

The importance of thermal disorder and electronic occupation for the T-dependence of the optical conductivity in FeSi and MnSi

open access: yes, 2007
The spectral weight (SW) for optical transitions in FeSi and MnSi are calculated as function of temperature by means of LMTO-LDA band calculations. The main effects, caused by structural disorder and electronic Fermi-Dirac distribution, act oppositely on

Electronic correlations in FeGa3 and the effect of hole doping on its magnetic properties [PDF]

open access: yes, 2014
We investigate signatures of electronic correlations in the narrow-gap semiconductor FeGa 3 by means of electrical resistivity and thermodynamic measurements performed on single crystals of FeGa 3 , Fe 1−x Mn x Ga 3 , and FeGa 3−y Zn y ...
