Abstract: The results of the investigation of the optical properties and calculations of the density of states

N (E)

$N(E)$ of the Heusler alloys Co

_{2}

$_{2}$ Cr

_{1 - x}

$_{1-x}$ Fe

_{x}

$_{x}$ Al (

x

$x$ = 0, 0.4, 0.6, 1.0) have been presented. It has been found that the band spectrum substantially changes, especially in the vicinity of the Fermi level, due to the concentration transition from Co

_{2}

$_{2}$ FeAl to Co

_{2}

$_{2}$ CrAl. These changes are accompanied by significant changes in the optical properties. The optical properties of the Co

_{2}

$_{2}$ FeAl alloy are typical of metals. The anomalous behavior of the optical properties of the alloys with

x

$x$ = 0, 0.4, and 0.6 is determined by the electronic states at the Fermi level.

Keywords: Fermi Level, Infrared Region, Boron Carbide, Interband Transition, Static Conductivity.
