N2 - Pure Pr1.5Ce0.5Sr2NbCu2O10 is not superconducting and magnetic susceptibility data reveal two magnetic anomalies at T(1)=11 and TN(2)=54 K. For the doped Pr1.5Ce0.5Sr2Nb(Cu1-xMx)2O10 where M=Fe,Zn,Cd, Ni and Ga, significant changes were observed only for the second peak which is extremely sensitive to the dopant concentration and shifted to higher temperatures. For a given M, TN(2) increases with the nominal dopant concentration. The largest shift is observed for M=Fe, e.g. for x(Fe)=0.05TN(2)=117 K. No specific correlation could be found between the temperature shift and the character of the dopant M. For substitutions made outside the CuO2 planes no change in TN(2) occurs.
