Electronic band structure of MnxCoyFe3-x-yO4 has been calculated in high symmetrical points and lines of the first Brillouin zone within the scope one-electron quasirelativistic pseudopotential approach. Atomic potential form-factors have been calculated in accordance with modified LCAO method. Dependence of energy gap Eg=Eg(x,y) against Mn, Co and Fe concentrations is calculated and presented.
