Doping effect on the evolution of the pairing symmetry in n-type superconductor near antiferromagnetic phase boundary

We present the investigation results of the in-plane ρ(T) resistivity tensor at the temperature range 0.4–40 K in magnetic fields up to 90 kOe (H || c, J || ab) for electron-doped Nd₂₋xCexCuO₄+δ with different degree of disorder near antiferromagnetic–superconducting phase boundary. We have experime...
