Correlation level in superconducting Sr2Ru04 system studied by ab-initio LSDA & LSDA+U calculations

We have calculated the electronic structure of Sr2Ru04 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. Calculations are performed in two different approaches: LSDA and LSDA+U. By applying U, we have aimed to measure the electrons correlation near Fermi surface. Thereupon, we will answer if this system realm on the correlated systems region or not?
