Both charge-ordered and magnetic domains produced in LuFe 2O 4, which have attracted significant attention due to the interplay of electronic and magnetic degrees of freedom, have been studied using transmission electron microscopy techniques. Dark-field images, obtained using a weak satellite reflection, revealed the nanometer-scale charge-ordered domains, which were observed over a wide temperature range below T CO (critical temperature of charge ordering; ∼310 K). Electron holography demonstrated an aspect of the long-range magnetic order wherein the magnetic flux lines were completely parallel to the c axis of LuFe 2O 4, in a specimen cooled to 17 K under an applied magnetic field. In contrast, there was no appreciable magnetic signal observed in a specimen cooled in a negligible magnetic field. These observations provide useful information for further understanding of the complex magnetic phase transitions in this compound.
