N2 - We report experimental data about the influence of Zn, Ga and Ni substitution of Tc of the electron doped system Nd1.85Ce0.15Cu1-yMyO4-δ, 0≤y≤0.15. The relative suppression of Tc for a given dopant concentration decreases from Ni to Ga to Zn. Superconductivity is totally suppressed above y=0.01, 0.03 and 0.05 for M= Ni, Ga, Zn, respectively. The solubility of M=Fe in the matrix is extremely small. The effect of M=Ga3+ on Tc is similar to that of Ce4+. We compare doping results for magnetic and nonmagnetic ions and discuss the origin of the depression of Tc. The effect of these dopants on Tc in the Nd-Ce-Cu-O system is completely diffrent from that observed in the La-Sr-Cu-O system.
