摘要：

Pure Pr1.5Ce0.5Sr2NbCu2O10 is not superconducting and magnetic susceptibility data reveal two magnetic anomalies at T(1)=11 and T-N(2)=54 K. Pr1.5Ce0.5Sr2Nb(Cu(1-x)M(x))(2)O-10 where M=Fe,Zn,Cd, Ni and Ga, were observed only for the second peak which is extremely sensitive to the dopant concentration and shifted to higher temperatures. For a given M, T-N(2) increases with the nominal dopant concentration. The largest shift is observed for M=Fe, e.g. for x(Fe)=0.05 T-N(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 T-N(2) occurs.
