Abstract

A modified analytical Aslamazov-Larkin formula for the temperature dependence of the fluctuation conductivity near the critical temperature T c is obtained for two-band superconducting compounds on the basis of linearized equations of the two-band Ginzburg-Landau theory. The results are compared to experimental data for the high-T c superconductor compound Bi2Sr2CaCu2O8 + δ.
