Neutron diffraction study of crystal structures and magnetism in PbRuO3 perovskite


We have synthesised the ill characterised perovskite PbRuO3 at high pressure and temperature. Synchrotron powder x-ray diffraction shows the room temperature structure to be orthorhombic as reported previously, and a transition to a lower symmetry phase at 75 K is also observed. Magnetisation measurements show evidence for a transition to a long range ordered state below 75 K. We request two days of GEM time in order to identify superstructure peaks resulting from oxygen displacements in the presence of heavy elements and to determine the ordered magnetic structure below 75 K. The high flux of GEM is required due to the extremely small sample (ca. 30 mg) synthesised at high pressure.
