摘要

Magnetic measurement and powder X-ray Rietveld analysis are performed on oxygenated Pri_1.5Ba_1.5Cu₃O_7.2 cuprate. This tetragonal compound with lattice parameters a = 0.38916 nm and c = 1.16177 nm is found to form the TlBa₂CaCu₂O₇ 1212-type structure when written as Cu[Ba_1.5Pr_0.5]PrCu₂O_7.2. Low temperature magnetic data indicate that anomalous Pr order temperature T_N(Pr) decreases from 18 K for orthorhombic PrBa₂Cu₃O_6.9 to 10.5 K for Pr_1.5Ba_1.5Cu₃O_7.2. The increasing Pr-O bond length with decreasing TN indicates that Pr ordering is closely correlated with the wave function overlap between Pr-4f orbital and O-2p_π orbital in the CuO₂ bi-layers.
