The electronic structure of oxides

The electronic structure of manganites is revisited on the basis of density-functional calculations. crystal-field splitting, magnetism, Coulomb repulsion, Jahn-Teller distortions will be described. The complexity of the oxides is raised in small steps starting from simple oxides in order to provide an intuitive understanding of the individual effects and how they appear in "real" materials.
