Iron coordination in liquid FeAl2O4.

The structure of aerodynamically levitated liquid FeAl2O4 was measured by neutron diffraction with isotope substitution (NDIS). Classical and ab initio molecular dynamics simulations were performed and their results were found to be in close agreement with each other and the NDIS data. The results reveal that molten FeAl2O4 may be considered as an ionic liquid without any preference for particular short-range structural motifs.
