There is a remarkable asymmetry between Ni and Zn substitution in the hole-doped and the electron-doped high-Tc cuprates. We propose that Ni-substitution of Cu in the electron-doped high-Tc cuprates be described by the Abrikosov-Gor'kov theory of magnetic impurities in s-wave superconductors. In particular, the low-temperature magnetic penetration depth shall tell if the pure magnetic scattering limit applies.
