摘要: Ordered states of a periodic Anderson Hamiltonian with large Coulomb correlation and orbital degeneracy localized levels are theoretically investigated. When the number f electrons is nearly one per site, when exchange interaction antiferromagnetic as whole, it predicted that an type ordering occurs in order at certain low temperature accompanied by lattice distortion due to Jahn-Teller effect, ferromagnetic or spin, if occurs, lower temperature. One most characteristic features this ordered state strong coupling between moments spin ones. It tried explain experimental data CeB 6 model quartet ground multiplet levels.
