摘要：

We investigate the magnetic phase diagram of the two-dimensional model for e,, electrons which describes layered nickelates. One finds a generic tendency towards magnetic order accompanied by orbital polarization. For two equivalent orbitals with diagonal hopping such orbitally polarized phases are induced by finite crystal field. (c) 2005 Elsevier B.V. All rights reserved.
