Abstract: | First principles calculations have been performed to study the electronic and magnetic structures of double perovskites Ca2MWO6 (M=Co, Ni) using full potential linearized augmented plane wave method. The density of states and spin magnetic moments are calculated and we have examined the valence states of Co, Ni and W ions. The results predict the half-metallic ground state of Ca2CoWO6 and the insulating nature of Ca2NiWO6. |
