Features of Optical Absorption Spectra of GdFe2 and LuFe2 Intermetallic Compounds

Аннотация

The optical properties of binary GdFe₂ and LuFe₂ compounds are studied by the ellipsometric method in the 0.22–17 μm spectral range. A number of spectral and electronic characteristics are determined. The experimental dependences of optical conductivity in the light quantum absorption region are interpreted based on previously published calculations of electronic states densities.
