Abstract

We review some of the relevant physical properties of the transition metal mono-silicides with the FeSi structure (CrSi, MnSi, FeSi, CoSi, NiSi, etc) and explore the relation between their structural characteristics and the electronic properties. We confirm the suggestion orginally made by Pauling, that the FeSi structure supports two quasi-atomic d-states at the transition metal atom. This shell contains from 0 to 4 electrons in the sequence CrSi to NiSi. In FeSi the two quasi-atomic d-electrons are responsible for the high temperature S=1 state, which is compensated for T=0 by two itinerant electrons associated with the Fe-Si resonance bonds.
