Abstract
Two recently proposed models for the defect structure of tin-doped α-Fe2O3 have been assessed using interatomic potential calculations. The results show that a structure involving tin (or titanium) partially substituting at the octahedral iron sites as well as partially occupying the empty interstitial octahedral sites in corundum-related α-Fe2O3 is more favourable than an alternative model in which the tin (or titanium) ions only occupy the empty interstitial sites.
