We have calculated the electronic structure of Sr2RuO4 using the full potential linearized augmented plane wave method in the spin polarized local density approximation. By this calculation, we identify the contribution of different electronic states near Fermi surface and study some electronic parameters like crystal electric field, exchange splitting, and hybridization between different atoms...
