- Abstract
- The paper presents the results of measurements of the current-voltage characteristics (IVC’s) in the electron-doped layered superconductor NdCeCuO and the results of the scaling analysis of the () 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 NdCeCuO with = 0.15 and SmCeCuO exhibit a non-monotonic nature of the d-wave symmetry order parameter associated with the coexistence of superconductivity and fluctuations of antiferromagnetic spin excitations.
