Abstract

Pure Pr_1.5Ce_0.5Sr₂NbCu₂O₁₀ is not superconducting and magnetic susceptibility data reveal two magnetic anomalies at T(1)=11 and T_N(2)=54 K. For the doped Pr_1.5Ce_0.5Sr₂Nb(Cu_1-xM_x)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, T_N(2) increases with the nominal dopant concentration. The largest shift is observed for M=Fe, e.g. for x(Fe)=0.05T_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.
