摘要

Full-potential linearized augmented plane wave and local orbital method calculations were performed for Fe2TiSn in order to investigate the optical properties and to show the origin of the different optical transitions. It is found that the band gap is indirect for Fe2TiSn. Then our calculated reflectivity spectra are in good agreement with the experimental results. On the other hand, the contributions of various transition peaks are analysed from the imaginary part of the dielectric function. Furthermore, the different optical properties have been investigated.
