Electronic Structure and Optical Properties of the FeAl2 Compound

Abstract

The electronic structure and optical properties of the binary intermetallic compound FeAl2 have been studied. Spin-polarized calculations of the electronic structure have been performed and the magnetic moments of atoms have been determined. Using the method of ellipsometry, the optical characteristics of material have been measured in a spectral range of 0.22–15 μm. It is shown that the experimental interband optical conductivity of the compound is satisfactorily interpreted based on the calculated density of electronic states.
