Phase diagram of an extended Kondo lattice model for manganites: the Schwinger-boson mean-field approach
R. Y. Gu, Z. D. Wang, Shun-Qing Shen +1
We investigate the phase diagram of an extended Kondo lattice model for doped manganese oxides in the presence of strong but finite Hund's coupling and on-site Coulomb interaction.…

An effective Hamiltonian for an extended Kondo lattice model and a possible origin of charge ordering in half-doped manganites
Shun-Qing Shen, Z. D. Wang
An effective Hamiltonian is derived in the case of the strong Hund coupling and on-site Coulomb interaction by means of a projective perturbation approach. A physical mechanism for…

Antiferromagnetism and phase separation in electronic models for doped transition-metal oxides
Shun-Qing Shen, Z. D. Wang
We investigate the ground state properties of electronic models for doped manganites and nickelates. An effective t - J like Hamiltonian is derived from the case of strong Hund cou…
