| Abstract | A detailed study of the effect caused by the partial substitution of Er by Ce on fluctuation conductivity of the Er(1-x)Ce(x)Ba(2)Cu(3)O(7-delta); 0 <= x <= 0.10; is presented. The combined experimental results of structural and electrical measurements indicate that Ce substitutes Er for x <= 0.10 with no significant structural distortions. However, there is suppression of the superconducting state with zero-resistance state at temperatures >= 86.3 K. The results were analyzed in terms of the temperature derivative of the resistivity and the logarithmic temperature derivative of the conductivity to identify power-law divergences of the conductivity. The data revealed the occurrence of a two-stage intragranular-intergranular transition. Above the critical temperature, the Gaussian and critical regimes were observed. Also, from the critical exponents analysis, we observed a splitting of the pairing transition for Ce-doped samples, suggesting the occurrence of a phase separation. On approaching the zero resistance state, our results showed a power-law behavior that corresponds to a phase transition from a paracoherent to a coherent state of the granular array and which does not depend on Ce doping. | |||
