DOIAbstract
The optical constants of Ni3Al from 0.5 to 5.3 eV have been determined by means of spectroscopic ellipsometry at room temperature under ultra-high vacuum conditions. Measurements were performed on a single crystal and a polycrystalline sample, which gave identical results. The results are compared with optical properties calculated from band-structure calculation. The experimental results are in good agreement with the predictions from the band-structure calculation
