- Title
Anomalous temperature dependence of the order parameter of a superconductor with weakly correlated impurities.

- Abstract
It is shown that weak correlations between pair-breaking impurities in superconductors influence the temperature dependence of the order parameter within the Ginzburg-Landau region if correlation radius of impurities R is greater than the coherence length of the superconductor ξ. The dependence of the square of the average order parameter on a temperature difference T − T changes its slope in a region $$ \xi _0 \sqrt {{{T_c } \mathord{\left/ {\vphantom {{T_c } {\left( {T_c - T} \right)}}} \right. \kern-\nulldelimiterspace} {\left( {T_c - T} \right)}}} \sim R $$. The influence of correlations of impurities on other thermodynamic properties of superconductors is discussed.
