Electronic structure peculiarities of the solid solutions of transition metals in Cr

Electronic structures of the solid solutions of transition metals (Ti, V, Mn, Fe, Co, Ni, Cu; Nb, Mo; Ta, W) in Cr have been investigated using the LMTO (linear muffin-tin orbital) calculation method. The energy dependences of the density of electronic states have been calculated for the supercell containing 16 atoms. It is shown that the doping with transition metals leads to the splitting of the chromium main 3d-peak into two sub-bands due to the formation of charge density waves. It is proved that the nesting model is not applicable the considered Cr alloys.
