Abstract

We have studied the effect of varying temperature and Co substitution on the low-energy electronic structure of FeSi by photoemission spectroscopy. We have observed that the density of states (DOS) of FeSi is reduced at low temperatures over a wide energy range of ∼50 meV below the Fermi level (EF), which is the energy scale observed by the magnetic, transport and optical measurements. The reduced DOS is completely recovered with increasing temperature but only partly, i.e., predominantly near EF, with Co substitution, again consistent with the transport properties.
