            Abstract : 
The responses of several kinds of iron-oxides in the terahertz (THz) frequency region are investigated. In addition, we developed a technique for the thickness evaluation of magnetite layers on steel plates using terahertz reflectance measurements following the laser-annealing of the sample.
