ÉTUDE DES PROPRIETES PHYSIQUES DE LA DOUBLE PEROVSKITE EN PHASE CUBIQUE

Abstract

The first principle calculations were used to study the structural, electronic and magnetic properties of the alloy Ba2EuSbO6 using full-potential lirearized augmented plane waves (FP-LAPW) method based on the density functional theory (DFT). The potential of exchange and correlation is treated by the generalized gradient approximation (GGA-PBE) for two states, non-magnetic state (NM) and ferromagnetic state (FM).The results obtained show that the compound is stable in the ferromagnetic state (FM). The results obtained for the density of states and band structure revealed that our compound has a metallic character and is a good candidate for spintronics applications. The study of magnetic properties, we found that the major contributions of the total magnetizations are localized at Eu atoms.
