Resonant inelastic x-ray scattering study of hole-doped manganites La1-xSrxMnO3 (x=0.2 and 0.4)
K. Ishii, T. Inami, K. Ohwada +8
Electronic excitations near the Fermi energy in the hole doped manganese oxides (La1-xSrxMnO3, x=0.2 and 0.4) have been elucidated by using the resonant inelastic x-ray scattering…
Orbital excitations in CMR progenitor of LaMnO3 studied by resonant inelastic x-ray scattering
T. Inami, S. Ishihara, H. Kondo +8
We report resonant inelastic x-ray scattering experiments of the orbital ordered manganite LaMnO3. When the incident photon energy is tuned near the Mn K absorption edge, the spect…
Temperature dependence of the resistivity in the double-exchange model
Satoshi Ishizaka, Sumio Ishihara
The resistivity around the ferromagnetic transition temperature in the double exchange model is studied by the Schwinger boson approach. The spatial spin correlation responsible fo…
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…
