Re-examination of orbital ordering in LaMnO $_{3}$ : Electron-electron and electron-lattice interactions

Satoshi Okamoto, Sumio Ishihara, Sadamichi Maekawa

The interactions between $e_{g}$ orbitals in neighboring sites are investigated in LaMnO $_{3}$ by taking into account virtual exchange of electrons and phonons. The spin and orbital or…

Theory of Raman Scattering from Orbital Excitations in Manganese Oxides

S. Okamoto, S. Ishihara, S. Maekawa

We present a theory of the Raman scattering from the orbital wave excitations in manganese oxides. Two excitation processes of the Raman scattering are proposed. The Raman scatteri…

Field-Induced Two-Step Phase Transitions in the Singlet Ground State Triangular Antiferromagnet CsFeBr $_{3}$

Y. Tanaka, H. Tanaka, T. Ono +7

The ground state of the stacked triangular antiferromagnet CsFeBr $_{3}$ is a spin singlet due to the large single ion anisotropy $D (S^{z})^{2}$ . The field-induced magnetic ordering in th…
