Charge and Spin Ordering in the Mixed Valence Compound LuFe2O4

arXiv:0812.3575 · doi:10.1103/PhysRevB.81.134417

Abstract

Landau theory and symmetry considerations are invoked to give a unified treatment of charge and spin ordering in the mixed valence compound LuFe2O4. In particular, the unusual evolution of charge ordering correlations can be explained by invoking phonon mediated interactions.
