On the multi-orbital band structure and itinerant magnetism of iron-based superconductors

This paper explains the multi‐orbital band structures and itinerant magnetism of the iron‐pnictide and chalcogenide superconductors. We first describe the generic band structure of a single, isolated FeAs layer. Use of its Abelian glide‐mirror group allows us to reduce the primitive cell to one FeAs...
