Resumo

The paper presents the results of measurements of the current-voltage characteristics (IVC’s) in the electron-doped layered superconductor Nd2–xCexCuO4 and the results of the scaling analysis of the U(I) dependence for a large set of layered HTSC’s. It is shown that the IVC’s of hole-doped compounds indicate a monotonic behavior of the d-wave symmetry order parameter, while the IVC’s of electron-doped compounds Nd2–xCexCuO4 with x = 0.15 and Sm2–xCexCuO4 exhibit a non-monotonic nature of the d-wave symmetry order parameter associated with the coexistence of superconductivity and fluctuations of antiferromagnetic spin excitations.
