Abstract

The magnetic order of Pr ions in polycrystalline, tetragonal PrBa ₂Cu₃O_6.2 has been studied by neutron-diffraction measurements. The basic ordering consists of an antiferromagnetic arrangement with the propagation vector k=[1/2, 1/2, 1/2], but the magnetic ordering is imperfect due to finite correlation length ξ_c=(10±1) Å along the c axis. The Néel temperature is determined to be T_N=(12±1) K, and the magnetic saturation moment of the Pr ions turns out to be (1.9±0.2) μ_B. The distance Pr-O(2) compared in several related perovskite-type Pr compounds correlates with the Néel temperature in accordance with the superexchange interaction.
