制备了有序钙钛矿化合物Ba2PrRuO6，并对其磁性进行了研究。150 K下测得的中子衍射谱Rietveld分析表明，Pr3+和Ru5+离子在钙钛矿ABO3的六坐标B位上有序排列，Ba2PrRuO6属于P21/n空间群，a = 6.0063(5), B = 5.9863(4), c = 8.4677(7) a和90.04(2)°。磁化率和热容测量表明，该化合物在117k以下转变为反铁磁态。在7 K下测量的中子衍射图确定其磁性结构为I型，Pr3+和Ru5+的磁矩分别为2.2(1)和2.0(2)µB。在晶体场分裂理论计算的基础上，讨论了它们的取值。
The ordered perovskite compound Ba2PrRuO6 is prepared and its magnetic properties are investigated. The Rietveld analysis of the neutron diffraction profiles measured at 150 K shows that the Pr3+ and Ru5+ ions are arranged with regularity over the six-coordinate B sites of the perovskite ABO3 and that Ba2PrRuO6 belongs to space group P21/n, with a = 6.0063(5), b = 5.9863(4), c = 8.4677(7) A and 90.04(2)°. The magnetic susceptibility and the heat capacity measurements show that this compound transforms to an antiferromagnetic state below 117 K. From the neutron diffraction patterns measured at 7 K, the magnetic structure is determined to be of Type I and the magnetic moments of Pr3+ and Ru5+ are estimated to be 2.2(1) and 2.0(2) µB, respectively. Their values are discussed on the basis of theoretical calculations for the crystal field splitting.
