Doping dependence of the exchange energies in bilayer manganites: Role of orbital degrees of freedom

G. Jackeli, N. B. Perkins

Recently, an intriguing doping dependence of the exchange energies in the bilayer manganites $L a_{2 - 2 x} S r_{1 + 2 x} M n_{2} O_{7}$ has been observed in the neutron scattering experiments. Th…

Spin-1 effective Hamiltonian with three degenerate orbitals: An application to the case of V $_{2}$ O $_{3}$

S. Di Matteo, N. B. Perkins, C. R. Natoli

Motivated by recent neutron and x-ray observations in V $_{2}$ O $_{3}$ , we derive the effective Hamiltonian in the strong coupling limit of an Hubbard model with three degenerate t_{2g}…
