Abstract: Al-doped and barium ferrite powders were synthesized using the sol-gel autocombustion method. The optical property and spectroscopy of Al-doped and barium ferrite were studied based on terahertz time-domain spectroscopy (THz-TDS). The power absorption and refractive index of the Al-doped and barium ferrite were measured. The result shows that Al-doped decreases the refractive indices of barium ferrites, while the refractive indices of barium ferrites samples decreases with increasing frequency, and Al-doped leads to decrease of the refractive indices.

Key words: Al-doped, barium ferrite, terahertz time-domain spectroscopy (THz-TDS)
