Direct Evidence of Fe2+/Fe3+ Charge Ordering in the Ferrimagnetic Hematite-Ilmenite Fe1.35Ti0.65O3-d Thin Films


Here we report on the direct experimental evidence of Fe2+/Fe3+ charge ordering at room temperature in hematite-ilmenite Fe1.35Ti0.65O3-d epitaxial thin films grown by pulsed laser deposition, using aberration-corrected scanning transmission electron microscopy (STEM) coupled to high-resolution energy electron-loss spectroscopy (EELS).
