Two Ferromagnetic States in Magnetoresistive Manganites - First Order Transition Driven by Orbitals -
S. Maekawa, S. Ishihara, S. Okamoto
A systematic study of the electronic structure in perovskite manganites is presented. The effective Hamiltonian is derived by taking into account the degeneracy of orbitals a…

Theory of Orbital Excitation and Resonant Inelastic X-ray Scattering in Manganites
Sumio Ishihara, Sadamichi Maekawa
We study theoretically the collective orbital excitation named orbital wave in the orbital ordered manganites.The dispersion relation of the orbital wave is affected by the static…

Phase Diagram in Manganese Oxides
Ryo Maezono, Sumio Ishihara, Naoto Nagaosa
We study theoretically the phase diagram of perovskite manganites taking into account the double degeneracy of the orbitals in a ion. A rich phase diagram is obtain…
