Research Abstract

LuFe2O4 is a typical multiferroic material, which exhibits the coexisting state of magnetic and ferroelectric orderings. Reflecting on frustration of charge ordering in a triangular lattice, the incommensurability of the ordering period changes. Besides,we performed the resonant soft x-ray scattering measurements on manganite superlattice. It is recognized that a ferromagnetism originates from the LaMnO$_3$ layers, although bulky samples of LaMnO3 and SrMnO3 originally shows antiferromagnetic structure.
