Abstract
Terahertz time-domain spectroscopy was per-formed on samples of the iron oxides alpha-hematite and magnetite. We were able to obtain the complex refractive index and dielectric constants. For alpha-hematite, an AFM resonance was observed at 0.13 THz. Although we did not find any resonance for magnetite, it was possible to observe spectral changes by decreasing the temperature. This suggests that TDS-THz may be a useful tool to detect corrosion on iron materials.
