摘要：

The magnetic order of Pr ions in polycrystalline, tetragonal PrBa2Cu3O6.2 has been studied by neutron diffraction measurements. The basic ordering consists of an antiferromagnetic arrangement with the propagation vector k over arrow pointing right = [1/2, 1/2, 1/2]. The three-dimensional magnetic ordering is imperfect due to finite correlation length xi(c) = 10 angstrom along the c-axis. The Neel 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) mu(B).
