概要

The charge ordering process of a mixed valence system LuFe<SUB>2</SUB>O<SUB>4</SUB> has been investigated using electron, X-ray, and neutron scattering techniques. We point out the unique features directly observed in the scattering patterns, and elucidate the physical origins of these unique features based on the theoretical treatment concerning cooperative ordering of extra chargefholes on Fe-sites. The results show clearly that the unique features in the scattering experiments are consistently explained only when the inter-charge interaction between the neighboring hexagonal layers is taken to be attractive.
