Abstract:
It is shown that weak correlations between pair-breaking impurities in superconductors influence the temperature dependence of the order parameter within the Ginzburg and Landau region if correlation radius of impurities $R$ is greater than the coherence length of the superconductor $\xi_0$. Dependence of a square of the average order parameter on a temperature difference $T_c-T$ changes its slope in a region $\xi_0\sqrt{T_c/(T_c-T)}\sim R$. Influence of correlations of impurities on other thermodynamic properties of superconductors is discussed.
