The change of the electronic structure and the optical properties of the metallic alloy FeCo is studied at the order–disorder transition. Energy‐band calculations for ordered and disordered alloys FeCo are performed by the KKR and the model Hamiltonian methods. In the model of direct and indirect transitions the optical conductivity is calculated. The calculations are in satisfactory agreement with the experimental data.
