Аннотация:A generalized alpha model for computing the superconducting parameters of real two-band superconductors is proposed based on an analysis of the properties of two-band equations in the theory of superconductivity. Using this model, we calculate the heat capacity and optical properties of Ba(Fe1 - x Co (x) )(2)As-2 superconducting compound and obtain the temperature dependences of the gaps and energies of the Leggett modes in the Mg1 - x Al (x) B-2 superconducting system. Good quantitative coincidence of the calculated data and experimental results is demonstrated.
