[en] Magnetic properties of the 1222-type structure compounds (Pb,M)(Sr,Pr)₂(Pr,Ce)₂Cu₂O₉ (M = Cu and Cd) and the 2222-type compound Bi₂Sr₂(Pr,Ce)₂Cu₂O₁₀ are reported. The magnetic susceptibility measurements reveal that Pr³⁺ moments are ordered antiferromagnetically around T_N(Pr) of 15-18 K for (Pb_0.5Mo_0.5)(Sr_0.9Pr_0.1)₂(Pr_0.7Ce_0.3)₂Cu₂O₉ (M = Cu and Cd), and at 22-24 K for Bi₂Sr₂(Pr_0.82Ce_0.18)₂Cu₂O₁₀. Except T_N(Pr), there is no other anomalous peak appearing in the susceptibility curve, which is different from the other reported 1222 MSr₂PrCu₂O₁₀ (M = Nb, Ta, Ga, In) systems. In the range of above T_N(Pr) to room temperature, the susceptibility curve can be well fitted by a Curie-Weiss law with an effective magnetic moment μ_eff of 3.12, 2.79 and 3.09 μ_B per Pr ion for (Pb_0.5Cu_0.5)(Sr_0.9Pr_0.1)₂(Pr_0.7Ce_0.3)₂Cu₂O₉, (Pb_0.5Cd_0.5)(Sr_0.9Pr_0.1)₂(Pr_0.7Ce_0.3)₂Cu₂O₉ and Bi₂Sr₂(Pr_0.82Ce_0.18)₂Cu₂O₁₀, respectively. The anomalous Pr magnetism and the suppression of superconductivity by Pr in the above compounds are discussed with the related Pr-containing 1212, 2212, 3212 and 214 compounds. (orig.)
