The oxygen vacancy induces a local anti-ferrodistortive-like oxygen-octahedron rotation, which leads to localized electronic states in the bandgap, giving an excellent explanation to the thermal ionization and optical transition observed experimentally. New insights into the atomistic and electronic structure of the oxygen vacancy in SrTiO(3) are presented …

This pattern was at erst baffling, since it showed that the 12 nearest neighbor spins (Mno is an NaCl structure; the Mn++ ions are thus in a face-centered cubic lattice) to a given spin are un-correlated with this spin; instead, the four separate simple cubic lattices of ...
