Magnetic structures upon ordering of eg orbitals in a square lattice. Aplesnin, S. S. & Moskvin, A. I. Journal of Physics: Condensed Matter, 20(32):325202+, 2008. Paper doi abstract bibtex The exchange mechanism effect on the ordering of electrons on e g orbitals in a two-dimensional Heisenberg model with exchange anisotropy for a S = 1/2 spin is determined. The regions of existence of long-range quasi-one- and two-dimensional antiferromagnetic order with the special exchange topology are calculated by a quantum Monte Carlo method. The Nèel temperature and quantum reduction of spin on site for an antiferromagnet with the stripe structure is estimated as a function of exchange anisotropy.
