Abstract
Magnetic and dielectric correlation in triangular mixed valence iron oxide RFe2O4 is discussed. The frustrated interaction for antiferromagnetic spins as well as charges realizes the auto-organized superlattice cell of iron ions. The characteristic charge and spin superlattice cell drives the magnetoelectric cross-correlation. The charge supercell detected with a resonant x-ray scattering measurement has an electric polarization that forms a class of new ferroelectrics.
