摘要: Optical study of 3d transition metal oxides with perovskite-type structure has revealed the variation their electronic element M. The low-energy feature is governed by states in M-O network. overall trend gap agrees well Zaanen-Sawatzky-Allen framework. We can also estimate Hund coupling constant and ligand field effect from optical spectra.
