Research Abstract

High magnetic field x-ray magnetic circular dichroism apparatus in conjunction with a 40 T pulse magnet and a soft x-ray absorption spectroscopy has been developed for magnetic investigations of underlying microscopic mechanisms of electromagnetic effects. By applying the world first novel apparatus to multiferroic systems, we succeeded in observations of valence specific magnetizations of di and tri-valence irons of LuFe2O4, determinations of spin and orbital magnetic moments of Fe(III) in CuFeO2 and element specific magnetic analyses of Tb and Mn in TbMnO3.
