Electronic and Magnetic Properties of Double Perovskite Ca2CrSbO6

First-principles calculations have been performed for the study of the electronic band structure and ferromagnetic properties of double perovskite Ca₂CrSbO₆. The density of states, total energy, spin magnetic moment, and charge density were calculated and analyzed in details. It is found that Ca₂CrSbO₆ has a stable ferromagnetic ground state and the spin magnetic moment per molecule is about 2.99μ_B. The chromium contributes the mostin the total magnetic moments. The results indicate that Ca₂CrSbO₆ is half-metallic.
