文摘
- •
Hematite thin films with different thickness were deposited by RF sputtering technique.
- •
X-ray diffraction patterns confirm the formation of hematite phase in all samples.
- •
Hysteresis curve at 300 K shows the presence of a weak-ferromagnetic phase.
- •
XPS show the presence of Fe2 + ions coexisting with Fe3 + ions.
