Effective three-band model for double perovskites
P. Petrone, A. A. Aligia
We start from a six-band model describing the transition-metal t2g orbitals of half-metallic double perovskite systems, such as Sr2FeMoO6, in which only one of the transition metal…

Metal-insulator transition in the double perovskites
A. A. Aligia, P. Petrone, J. O. Sofo +1
We construct an effective Hamiltonian for the motion of electrons among the transition metal ions of ordered double perovskites like Sr2FeMoO6. in which strong intra-atomic Coulomb…
