Electronic Properties of Complex Oxides

Complex oxides are of profound interest from scientific and technological point of view. Understanding their unique electronic properties requires a sophisticated treatment of the strong Coulomb interaction between electrons in well localized metal d- or f- orbitals and oxygen p states, which strongly hybridize with each other. This article will review the electronic properties of complex oxides and the state-of-the-art methods for investigating their electronic structures, whose applications transcend a wide area of scientific and technological disciplines, ranging from fuel cell electrodes and piezoelectric transducers to high temperature superconductors and spintronic devices.
