Abstract
The temperature dependencies of resistivity and thermopower in Eu1+xBa 2-xCu3Oy (x = 0 - 0.5) have been measured. The results obtained have b een analyzed on the basis of phenomenological theory of electron trans port in the case of the narrow conductive band. The using of the narro w-band model has enabled us to determine the band structure parameters for the samples with different x. The possible explanation of the T(c ) lowering with x increase has been proposed. It is concluded that the oxygen sublattice disordering has a determinant effect on band struct ure parameters and superconductive properties of LnBa2Cu3Oy-system.
