Mean-field phase diagram of interacting e_g electrons

Strongly Correlated Electrons 2009-11-11 v1

Abstract

We investigate the magnetic phase diagram of the two-dimensional model for e_g 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.
