Abstract

We have studied the electronic structure of FeSi by high-resolution photoemission. At room temperature the spectra show no energy gap while a gap opening was observed below ∼150 K accompanied by the gradual paramagnetic-to-nonmagnetic transition. From analysis of the spectral lineshape using a model self-energy, we find that considerable band narrowing occurs near the band edge, probably due to electron correlation, giving a qualitative explanation to the unusual electronic and magnetic properties.
