The conductor-insulator transition as a result of antiferromagnetic ordering in monosulfides of 3d metals
The electron-energy structure of the structure of monosulfides of 3d metals is calculated using a modified LAPW + lo technique that allows for the antiferromagnetic ordering in different crystallographic layers. It is shown that the splitting of d-states of the transition metal with regard to the antiferromagnetic ordering in layers leads to a transition of VS, MnS, CoS, NiS, and FeS monosulfides in the troilite structure from metallic to semiconducting state.
