Systematics of Optical Gaps in Perovskite-Type 3d Transition Metal Oxidest .. The low-energy feature is governed by electronic states in the .-O network. The overall trend of the gap variation agrees well with the Zaanen-Sawatzky-Allen framework. We can also estimate the Hund coupling constant and ligand field effect from the optical spectra.

Optical Spectroscopy on the Mott Transition in Perovskite-Type Titanatesal hole-doping. In the barely metallic state near such a filling-controlled Mott transition, strong enhancement of the carrier effective mass has been observed. Optical spectroscopy has revealed the change of electronic structures with doping and its dependence on the strength of electron correlation.

Anomalous Physical Properties Around Magnetic and Metal-Insulator Transitions — A Spin-Fluctuation TAnomalous physical properties or non-Fermi liquid behaviors around the magnetic instability in strongly correlated electron systems, such as d-metals, heavy electron systems and metallic states around the Mott transition point, are discussed in a unified way in terms of the theory of spin fluctuations.
